Overcome your anxiety

Anxiety disorder is one of the mental illnesses we encounter most frequently. It resembles depression because most depressive patients often feel anxious. But its dominant symptom is not a depressive mood but anxiety.


Anxiety is one of the human emotions we have to get along with since the ancient era. As we feel anxious, we can examine a plan to carry out the project. Anxiety makes you distant from potential dangers. Thus, this annoying emotion is essential for survival.

However, excessive anxiety is not only useless for your life but also harmful. Some patients cannot take a train because of the fear they encounter an accident. Hypochondriac patients check their physical status repeatedly, unnecessarily, and it leads them rather more anxious.

Researchers suggest anxiety disorder is also a serious disorder as well as depression. It lowers our productivity and even reduces life expectancy.

Then, how can we overcome anxiety?

Cognitive behavioral therapy, as well as medication, is said to effective to reduce your anxiety level. But there are not so many therapists available in the clinical setting. In Japan, few patients meet a specialist for proper treatment.

One simple but effective option against anxiety is not to address it. “Do it badly” is a strong strategy if you suffer from anxiety. Perfectionism is a common obstacle to keep you from relaxation.

The Conversation: Surprising ways to beat anxiety and become mentally strong – according to science

In this article above, you are recommended to “wait to worry,” as well as doing badly. Indeed, it is said that 90% of your worries are not realized. The rest 10% is to be addressed seriously. But it is not too late to treat it when you notice that they are real challenges.

It is also a good solution to worry about others instead of yourself. When you are in the cloud of anxiety, you cannot see other persons. When you think of others, you may be free from unreal fears of your surroundings.

In Japan, Morita therapy was born to overcome anxiety. Morita said that you have to let your anxiety as it is. His idea is consistent with the concept of mindfulness. I believe Morita therapy is one of the strongest option of treatment strategy of anxiety disorder.

Logan, impressive but destructive as well as intrusive

I saw "Logan" in cinema. It is the last movie of Wolverine acted by Hugh Jackman.


It describes the US in 2025. For a couple of decades, there have been no mutants born. Thus, mutants are in the peril of extinction. And Wolverine is also suffering from aging. For unknown reasons, his healing factor is no more effective.

Furthermore, to be surprised, Professor X has dementia due to Alzheimer's disease. He misconducted the telepathy to damage large people one year ago. Since then, he has been forced to take tranquilizers regularly by Wolverine.

What a dystopia it is! Logan begins with such a miserable opening.

And, he finds Laura, a mysterious girl with mutant power. Her ability is quite similar to Wolverine's. And her guardian begs Wolverine to bring her to Eden, a utopia for mutants.

Professor X has expected that she would be hope for all mutants. But Wolverine is skeptical to the existence of Eden. And they are attacked by Donald Pierce, a cyborg, and his troop.

In the middle of the movie, Wolverine notices that Eden is merely an image in the comic book of X-MEN. He feels desperate. But, after reaching the place of Eden, he is astonished to know the true meaning of it.

Eden itself does not exist. But, there are some guys who believe it. And they can build Eden.

The atmosphere of this movie is quite dark. Most fans of X-MEN do not want to see old Wolverine and fool Professor, I guess. And I believe that the director deliberately wanted to terminate the X-MEN series with launching this work.

Laura is a charming girl. But she does not know most rules of the community because no one told her. Her rude and merciless behaviors are often annoying. In addition, she is frequently involved in gore scenes. I do not like making a young actress play such bloody actions.

The history of X-MEN is ended by Logan. I hope to see a new series some day. And it would have been better if I had been able to see Ian McCarran in this film.

Personal Rating: 3 (fair)

American student arrested to be dead in North Korea

Very recently, an American student was victimized by North Korean force.


Otto Warmbier was a 21-year-old student at the University of Virginia. He was arrested by the police in North Korea for "hostile acts against the state," according to the North Korean authority. Actually, he was said to have attempted to pilfer a propaganda poster. He was sentenced to 15 years forced labor.

And recently, the North Korea released him to the US because he became unconscious. At the time he was moved to the US hospital, he was in the coma state. North Korea said it was due to contracting botulism and taking a sleeping pill. Finally, he died without recovering the consciousness.

The Washington Post: North Korea’s outrageous mistreatment of a U.S. student must not go unpunished

It is not surprising that the US media condemn North Korea. But, there are multiple points of view to be considered.

First of all, the report of North Korea is far from trustworthy. Many people, including me, suspect he was tortured to be dead in North Korea. It is rare botulism toxin and a sleeping pill takes a life of a healthy young man.

Second, even if he committed a crime in North Korea, I never believe his act deserves to 15 years imprisonment. But, there are considerable variations in the penal legislation among nations. We have to respect each country's culture unless it is insulting other people's right. And the human right is a concept more complicated than it looks.

And finally, I wonder why he was released. I do not believe the official report of North Korea that it was decided according to a humanitarian point of view. I would have been not surprised if North Korea had concealed the full facts and had reported that he was missing. Therefore, North Korea considered that it would be advantageous to release him. His fatal damage was not planned for North Korea, perhaps.

Anyway, I pray for Otto. And I hope there will never be next victims.

Grenfell Tower fire accident

In London, there was a fire accident on June 14th, 2017.


Grenfell Tower, an official apartment with 24 levels located in West London was surrounded by the firestorm. At least 79 people were dead in this incident.

The Telegraph: Grenfell Tower: 79 people now presumed dead in London fire, police confirm

Grenfell Tower was built in 1974. It is suspected that this building did not meet the standard of protection from fire. The residents had expressed a worry about fire. But the administrating company might ignore their complaint.

It seems that the fire was immediately spread to the full range of the building. It means that normal precaution was not equipped in this building. Sadiq Khan, the Mayor of London, said that it was a preventable accident caused by years of neglect by the local council and successive governments. Theresa May, the Prime Minister, announced the necessity of the entire investigation.

BBC News: Latest updates as fire recovery continues

London City has several old buildings. Aged infrastructure may be a risk for disaster. Two years ago, I saw a fire accident at Holborn. It might be caused by crippled electric hoses.

My past entry: Fire accident at Holborn, London

In Japan, the building standard was amended after some accidents. I expect London will be safer with detailed investigation of this sad event.

Macron's party won the general election

Recently, a general election of Parliament was conducted in France. As expected, Macron's party grabbed the victory.


In France, Parliament vote is carried out twice in each term. As a result, La République en Marche (LREM) which Macron belongs to got a total of 360 seats in the 577. Gaining the majority, Macron will administer the government with ease.

However, it does not mean most French people is on the side of Macron. His political ideology is rather central. Thus, his supporters are widely distributed from right to left. People who love nationalism but do not trust Le Pin also voted to LREM. As well, a part of supporters of Hollande, the ex-President, seems to have joined to LREM for the victory of this poll.

In addition, the turnout of this election was lowest ever before since the Fifth Republic was established. The voting rate was less than a half.

Aljazeera: France's Macron wins strong parliamentary majority

France24.com: Macron completes electoral grand slam amid record-low turnout

Some people suggested it means indifference of the citizens to the election. But, I believe one of the reasons was the high likelihood Macron's winning. People would not vote if noticing that their vote would have no impact on the outcome.

France is often subjected to a terror attack by ISIS and other extremists. The fact Macron won has multiple meanings. French citizens are rational and willing to seek a solution other than excluding immigrants. At the same time, they may have no panacea to fix the current situation. Macron's LREM will be facing a great challenge.

Healthy obesity is an illusion

Metabolic syndrome is one of the most important concepts for promoting your physical health. High blood pressure, hyperglycemia, hyperlipidemia, and visceral fat are called as "the death quartet," meaning significant risk factors for sudden death.


However, there are many people who are obese but not having unhealthy symptoms or abnormality. Are they need to lose the body weight?

The answer according to the clinical evidence is "yes." So far, some data have suggested that obesity is an independent factor of premature death.

And now, a result of a longitudinal study with a large sample size was published. The outcome shows that obese people have 50% higher risk of heart failure. Thus, there is no "healthy obesity."

The Guardian: No such thing as 'fat but fit', major study finds

However, only 50% increase of the risk is not so impressive. There are many other risk factors other than obesity. And genetic characteristics are also highly likely to influence the risk. It is unsure you should reduce the weight with accepting serious suffer.

In Japan, there is no word meaning "healthy obesity." Recently, "Pocchari" is used to suggest fat but pretty girls. But it does not include any meaning of health. Japanese are relatively difficult to become obese, perhaps due to genetic issues and diet style. Therefore, obese Japanese are seldom deemed as healthy.

Harm of social media: a study

In every era, a novel thing is subjected to criticism. And social media are not an exception.

A survey conducted by researchers at the University of Sheffield was published recently. According to them, social media such as Instagram, Twitter, and Facebook are harmful to youth's mental health.

The Guardian: Facebook and Twitter 'harm young people's mental health'

They examined several measures in thousands of participants. The result showed that social media users had less sleep and were more anxious. Girls also tended to have negative body image. They created a model formula to estimate the relationship between the time spent at social media and their life satisfaction. As a conclusion, some social media were harmful to the youth.

SSRN: Social Media Use and Children's Wellbeing

This paper is too difficult for me to examine its validity. Some economists were involved in this survey. On the other hand, psychiatric professionals were less engaged in this study. I think it is doubtful they could measure the participants' life satisfaction exactly.

In addition, there is a possibility of reverse causality. People who are indulged in social media tend to suffer from some kind of mental illness or dissatisfaction. Participants who use social media extremely much time can be addictive.

Indeed, some other researchers are doubtful to the validity of this study.

Furthermore, if social media is rather harmful to us, it is almost impossible to ban them from our daily life. Early exposure and education about how to treat them are essential.

Yoga recommended for patients with cancer

Yoga is recently focused as a way of relaxation in many developed countries. Its character is that you need no serious physical activity. Yoga technique is considered to burn your visceral fat in spite with rather a  series of slow movement. It means you can recommend yoga to elder people or patients with physical illnesses.


Here, a couple of studies are introduced in which yoga activity has reduced stress in patients with cancer. Participants felt less fatigued after yoga exercise.

The Guardian: How yoga could ease cancer patients' pain and fatigue

It is unsure this study is a controlled trial. But the in the second study participants were divided into two groups: exercise alone and exercise and yoga. The latter participants showed improved mood compared to the control. If it is a randomized control trial, this result may be reliable.

The mechanism of the effect on the mental activity of yoga is still under-investigated. Some researchers claim yoga activity reduces your cortisol level. But, it is not easy to measure the influence of yoga on internal cortisol.

Bitcoin falling

Yesterday, the price of Bitcoin corrupted all at sudden.


Recently, the price reached 3,000 USD. The magnitude was the highest ever before. Some people claimed the price would be 10,000 USD in a year.

However, its price is now under 2,500 USD.

What do you think about the vulnerability of Bitcoin value? I believe Bitcoin and the technology of blockchain are innovation and cryptocurrency will be an alternative figure of money. But, its volatility is still so high that most Bitcoin lovers are speculators. It will take a while before Bitcoin becomes a common way of transaction.

Dramatic decreasing of UK nurses from EU

After a historic vote of Brexit in the last summer, several changes has come in the UK. Among them, an issue of immigration is often focused. The UK had accepted a large number of immigrants so far. They have considerably contributed to the British economy and society. But, this situation will not be sustainable.


For example, the number of EU applies to work in the UK as a nurse is rapidly decreasing. In this April, only 46 applied from EU while there were 1,304 last July.

International Business Times: Number of EU nurses applying to work in UK has slumped by 96% since Brexit vote

The UK has been recognized as a resort for health workers. Many health care providers were willing to work in the UK. However, the current unclear situation seems to make potential workers hesitate to enter the UK. It is quite natural, I think.

As some politicians say, the UK government has to guarantee the position of current workers from the EU. In addition, it is necessary to keep the numbers of skilled workers, regardless of their home, for the future. To be honest, I am doubtful Brexit lovers exactly prospected this issue before the poll.

How to avoid the damage of a nuclear bomb

Recently, North Korea conducted provocative actions repeatedly. Despite the UN condemned it and requested calm and rational responses, we have become nervous about the possibility of the war.


Representing the public fear, there are some articles describing the method for evacuation. If a ballistic missile with a nuclear bomb, how should we do for minimizing the unfavorable outcome?

A golden rule is that you should lie down immediately after sensing the light or tremor. The first impact of a nuclear bomb is the heat wave. Subsequently, a blast of debris will come. Making your face down may decrease the risk of being hit by them.

As well, you should cover your ears with your hands. Your tympanums are easily broken when encountering an extremely loud noise.

On the other hand, it is the last idea recommended to stay in a car. You will be burned out with the car.

Business Insider: If a nuclear bomb explodes nearby, here's why you should never, ever get in a car

If you are in a building, keep you stay there. A thin wall of lead can block the radioactive wave.

Anyway, the war is the most stupid solution of a conflict. We are responsible for avoiding desperate results from the current situation.

Prospective students of Harvard dismissed due to the posts on Facebook

At least ten students got their permission to enter the class of Harvard in 2021 canceled. The reason was the contents they posted in a group chat on Facebook.

Independent: 10 students have Harvard acceptances withdrawn over Facebook memes

Members of the group created sexually or racially offensive description and graphics on the Facebook group. The Admission Committee of Harvard started to investigate what they had posted. After a deliberate investigation, at least ten prospected students were excluded from the list of 2021 class.


To begin with, I was a little surprised that the Harvard class in 2012 has been fixed now. I am not sure what the students posted exactly. Considering the fact that the dismissed students must be teens, the decision of the authority can be harsh. But, the issue of discrimination is very deep and serious. The seed of prejudice is born in the very early life stage. Harvard seemed not ignore their rude behavior.

Nonetheless, we have to reconsider how to treat the misconducts on the internet. Everyone have bitter memories they made a failure in the youth. However, what you have posted on the internet will last eternally. The right to be forgotten was discussed recently. We should be tolerant to misconducts in young people a little more.

Eating in front of a mirror makes you happy?

Eating alone is often deemed as a behavior of a solitary person. And we are unconsciously aware that we taste bad when eating alone. Indeed, studies have found that eating with others make us satisfied with the meal and eat more.


Recently, an interesting study was conducted to examine the effect of eating together. Participants were requested to eat in front of a mirror. Surprisingly, they ate more food and felt better of the taste as if they had been with other persons.

Hindustan Times: Eating alone in front of mirrors makes meals taste better: Study

The result is hardly trustworthy at a glance. If we are influenced by a mirror image of ourselves, it is so silly to make efforts for comfortable surrounding. But the system of our neural network and feedback is developed with a very simple structure.

But, considering the fact that few restaurants equip mirrors near to the guest's seat, I hardly believe the outcome of this study, nevertheless.

In addition, some people, especially with eating disorders, experience binge eating when alone. They often say their appetite becomes controllable in a dinner with close friends. Thus, eating together does not necessarily have an effect of growing your appetite. Eating is a complex behavior.

UK general election 2017

UK general election was held on June 8th, 2017. The result was shocking for Theresa May, Prime Minister of the UK.


The ruling Conservative Party lost 13 seats of Member of Parliament, whereas opposing Labor Party gained 32 seats, reaching 262. The Tory dropped from the absolute majority. It will continue to make a coalition with Democratic Unionist Party which had ten seats for keeping the majority.

May made an apology for this defeat and asked for support to her colleagues in the party.

The Telegraph: Live  Election results 2017: Theresa May says sorry to defeated Tory candidates as she eyes deal with DUP

It was May's intention to conduct a general election. Thus, the result was far from her expectation. Many people claim she should resign. But she denied the idea of dropping out.

I support her continuation despite admitting that her decision to make a vote was a failure. The UK is shaken before the Brexit and recurrent terrorism now. There are not so many politicians who can address this complicated situation.

Genetic treatment for asthma, a possibility

Asthma is one of the terrible respiratory diseases that can occur in many people. Its symptom is the disturbance in breathing. Patients suffer from the difficulty of absorbing the air, often causing crippled oxidation. The asthma attack can be fatal in infants, elder, or compromised patients.


Asthma is considered not as a respiratory disease, but as occurring due to an allergic reaction. NSAID, an anti-inflammatory drug is well-known as a material to cause an asthma attack. Hyperactivity of immune system can contribute to tightening the lower respiratory tracts in the patients.

Therefore, relaxing the allergic reaction can be a solution to treat asthma. The steroid is frequently used to asthma in a serious case.

And now, Australian researchers published that they have found a possibility of a decisive way to cure asthma.

Independent: Allergy treatment: Scientists claim breakthrough that could lead to cure for all intolerances

According to the researchers in Queensland University, they successfully used the genetic modification in mice to reduce the allergic response to egg white. The egg is one of the substances which frequently bring an allergic reaction in the human.

Unfortunately, I could not find the original article published in JCI Insight. And my specialty is far from genetics. So, I cannot evaluate the validity of their experiment. According to the media, the responses toward the result the researchers had published were various. The researchers admit it will take several years to begin the clinical trial.

If genetic treatment for allergic reaction is utilized, it will be an innovation and will rescue massive patients. But in my sense, there are many barriers before the expecting outcome.

Death is not a so sad event? It is!

All we will die some day. It is the destiny of the human being.


And death has been a subject to be feared since the modern society was established. We believe that death is inevitable, but want to survive as far as possible.

Many people believe that we will be in full of fear at the end of life. But researchers at the University of North Carolina claim it is not true. People near to death feel happy, according to them.

Independent: Dying people are surprisingly happy about it, study finds

In this study above, the researchers found approximately a total of 600 blog posts written by patients near to death by cancer or amyotrophic lateral sclerosis. They examined the contents of each entry. For comparison, they recruited healthy volunteers, to ask them to write a blog with imagining that they are near to death. As a result, people near to death in real were considered to have made more positive ideas than healthy people.

Therefore, this result suggests that death is not necessarily a horrible or hopeless event, according to the author. If so, it will be relieving for people with diseases hard to treat. However, how is the validity of this study? In my opinion, this result is far from reliable, unfortunately.

First of all, the materials of this study are blog entries written by people with illnesses. There is possible room for selection bias in the methodology of this study. People who are willing to write a blog tend to intend to have a positive impact on the readers. Thus, they can pretend their mood and feel as glad and happy rather than sad and fearful. In addition, depressed people cannot write a blog, in general. Patients in severe medical condition are hardly able to write things, either.

I have seen studies which treated similar themes of this one. And the researchers did a face-to-face interview with the patients. A direct conversation represents the emotion of the subjects more precisely than the blog entries. Nonetheless, patients in a serious state could reject the interview.

Even considering the value of this study, I hesitate to trust the claim of the authors of this study. Death is still an arc enemy of human.

Elon Musk quits Trump's advisory panel

The decision of Donald Trump to withdraw the Paris climate deal made halation around the world.

He intended to protect domestic industry from burdening with several regulations about environmental issues. Business industry in the US, however, did not welcome his idea.

For example, Elon Musk, the founder of Tesla, and Robert Iger of Disney quitted the high-powered business advisory panel. The panel has been influential to the administration as several persons of importance in business industry are contained as the members.

The Guardian: Elon Musk and Disney boss quit Trump's business panel over Paris pullout

I guess they had been considering to abandon the panel since Trump won the Presidential election. Pulling out of Paris climate accord seems one of the good opportunities for them to declare the resignation.


In the 20th century, the identity of a company is to maximize the profit. During last some decades, leaders begin to consider the total benefit for the whole world prioritized to temporal benefit. Not only Elon Musk, but also Bill Gates, Mark Zuckerberg, and other famous billionaires are willing to devote their estate to the public good. I believe Trump's idea that domestic benefit should be prioritized is out of date.

On the other hand, many people have no more room to take care of other's benefit. Many ideologies are conflicting with each other. The response to Trump's decision reflects the current complicated situation.

Polypharmacy eases your blood pressure?

Recently, a group of British researchers made an interesting publication about the treatment of high blood pressure.


They combined four kinds of drugs: irbesartan, amlodipine, hydrochlorothiazide, and atenolol, with each of a quarter of usual dosage.

Irbesartan is an angiotensin II recepter blocker. Amlodipine is a traditional calcium channel blocker. Hydrochlorothiazide is a type of diuretic. And, atenolol is a typical beta blocker. Each of them is commonly used against hypertension. The researchers believe the combination of the four drugs is powerful enough to normalize most patients' blood pressure with less adverse effects. The result of a clinical trial was impressive.

Hindustan Times: Now, a ‘miracle pill’ for the treatment of high blood pressure

If this outcome is reliable, treatment for hypertension will proceed to the next stage. However, I am skeptical of this hypothesis. In the region of psychopharmacology, medical practitioners were willing to find an effective recipe of mixed several neuroleptic medications. But it resulted in a serious failure. Blocking several receptors in the brain using polypharmacy made patients dull and suppressed, but not calm. And patients were suffering from several long-lasting side effects.

Of course, usage of cardiovascular drugs is different from psychopharmacology. I expect researchers will optimize the effectiveness of the medication.

Dictation software in Japan

Nowadays, voice input is a common way to make a document. Siri, Cortana, and Google search can recognize what you say with accuracy. Some writers are fond of writing an article with their voice rather than the keyboard.

One of the advantages with voice input is the speed. Originally, QWERTY keyboard has been arranged to limit the typing speed because too fast typing could break the typewriter. On the other hand, voice input can translate your message to the manuscript almost at the real time.

In addition, with using voice input, you will never hurt your fingers and shoulders with typing. Touch typing is accustomed by several writers. But typing a series of words with fixed posture for a long time is considerably harmful to your health. Not a few writers are suffering from fingers and back pain. Before the spread of typewriters, writers were also annoyed to take a pen with tired fingers. Voice input releases you from such a troublesome habit.

However, voice input is still not so common in Japan. There are some reasons for it. One of the most decisive problems is the character of the Japanese language. There are many Kanji characters used in Japanese. And some of them shares the calling. For example, we name a fixed star, structure, editing an article, and rehabilitation of a criminal, as "kousei."

We usually distinguish them with seeing the Kanji. On the other hand, we need to identify which "kousei" the speaker mentions through considering the context. This task is quite difficult for a voice input program.

Also, "wa" can mean peace, sum, and traditional Japan, which is described with the Kanji. But, ring is pronounced "wa" too, with a different Kanji character.


Nonetheless, recent applications are so great that I can write a short article with voice input. "Dragon Speech" is an excellent software fully adapted to the voice input in Japanese.

Dragon Speech (in Japanese)

On the other hand, I hardly the voice input in English. My pronunciation is too bad to be promptly identified by machine. Rather, some Japanese English learners utilize the voice input software to correct their pronunciation.

Sexuality and diet: not so easy to understand

Gender identity is a novel and sensitive issue. American Psychiatric Association discussed whether homosexuality should be deemed as a disease or not in the process of establishing DSM-IV criteria. Finally, the members of the publishing team made a vote to determine this issue. Thus, there is still limited evidence to identify the scientific character of sexuality.


And, there are also some people claiming homosexual is a disease. Rita Strakosha is one of the researchers who suspect the relationship between sexual preference and daily diet. She claims that continuous taking of junk food makes you homosexual.

It is no doubt that her hypothesis ignited widespread criticism. Recently, she said that her idea was often misunderstood. She expressed that it is not so important whether homosexuality is a disease.

International Business Times: Author of 'study' claiming unhealthy lifestyle causes homosexuality says she's been misunderstood

I dare not to read through her article. It seems not needed to judge her hypothesis. As some researchers say in the article above, it is nonsense.

To begin with, sexuality is a complex idea derived from several factors. hormonergic reaction is only partially decisive to form your sexual identity. It is quite rude to explain the human sexual behaviors with only the biological factor. Moreover, diet and sleep have only limited role in determining the physiological reaction in the human.

In other words, she is apparently overestimating the effect of biological reaction in the human behavior. It is a common pattern observed in psychologists, in my experience. I prospect her hypothesis will not survive in the near future.

Oesophageal cancer, a desperate disease

I am a psychiatrist. I have treated several patients. Some recovered, others did not, unfortunately. In general, psychiatrists are rare to be satisfied with their treatment performance because the success rate of each therapy can be vaguely evaluated. In this meaning, I am often jealous to surgeons.


On the other hand, there several types of cancers, which are the main targets of surgery. Among them, oesophageal cancer is still a large enemy for practitioners.

The Conversation: Oesophageal cancer rates are rocketing - here’s what you need to know about the disease

Oesophageal cancer is hardly detected in the early stage. And many patients suffer from the problem about swallowing foods even if they survived the surgery. In addition to the treatment option of surgery, radiation therapy is also adapted to treat oesophageal cancer. As esophagus is located rather in the exterior area of the body, radiation looks useful at a glance. However, exposure to radiation causes you burning and other adverse effects.

When I was a medical student, the first patient I took charge of was an old man with oesophageal cancer. He was brave and optimistic. I learned many things from him. But the outcome of his treatment was not good, unfortunately.

Nowadays, many types of cancers have been defeated by newly treatments. But oesophageal cancer is still increasing. I hope some researchers will find an innovative way to cure this serious disease soon.

Trump will withdraw from Paris climate deal

Donald Trump is expected to declare the withdrawal from Paris climate agreement, according to the officers.

CNN: Trump expected to withdraw from Paris climate agreement

*Trump has officially declared the withdrawal.

Paris agreement was developed in 2015 for stabilizing the global climate change. More than one hundred of nations have joined in the deal. Its purpose is to fix the global warming, one of the most critical problems in the current world.


However, Trump was opposing the deal. He seems to believe the agreement is stupid and disadvantageous to the US. Withdrawal from the Paris agreement was one of his promise before the Presidential vote. Therefore, it is not surprising at all if Trump signs the Presidential Decree to abandon the deal.

To begin with, Trump believes that climate change is an illusion or hoax by agitators. His idea is out of the question. But, it is not easy to estimate the influence of the human activities on the climate exactly.

Interestingly, China will be cooperative with the EU to stress the importance of the deal to the US.

The Guardian: China and EU strengthen promise to Paris deal with US poised to step away

It is rare that China gets along with the EU, as well claiming the importance of the environmental issue. China is one of the greatest contributors to the air pollution. I guess, however, China itself recognizes that it should be treated as soon as possible.

As I wrote previously, environmental issues are quite difficult to be addressed collaboratively by multiple players because it is public goods.

My past entry: Climate is a public goods

Paris agreement is a historic decision of several countries sharing the deep concern to this issue. I hope it will be adequately adhered by many nations.

System trouble in British Airways

On May 27th, British Airways (BA), a leading aircraft company in the UK encountered a serious system trouble. It made all of the flights from Heathrow and Gatwick airport crippled. Thousands of passengers were trapped, to be forced to stay a night at the airport.


The trouble continued for some days. Now BA has declared a full recovery from the trouble, but there are still several flight plans badly influenced.

The cause of this trouble is not an external challenge, according to BA. If a person or organization with malicious intention had done this act, it would have been a critical problem not only the airline company but also the nation.

BA will compensate up to tens of millions GBP for damaged customers. Its stock price fell by four percent on the day of the incident.

The Guardian: British Airways owner loses £170m in value after IT meltdown

It is fortunate that nobody was injured in the accident. I can hardly imagine the magnitude of the damage if it were an atomic power plant to have been crippled. I expect BA to prevent the recurrence of this kind of problems.

Do not believe yourself

Every self-developing method shares an ideology. Say, "Believe yourself!"

It is a strong idea to trust your potential. Even if everything is terrible around you, the belief that you are OK will rescue you. You may have a power to change everything.

However, I do not this idea at all, to be honest. In other words, I do not believe myself.

My memory is quite fragile. My abilities are so limited that I have made several failures. And I was supported by many people around me.

Being confident is useful in some context, I admit. But, it brings you recklessness. Also, there are many people who hardly can themselves. Being confident is only a remedy effective in limited opportunities.

So, I do not believe myself. Instead, I believe everything is going well, by other powers.

Being opportunistic is a golden rule for better life. It has been proven that almost 90% of your worries would not be realized. Thus, being anxious is no more beneficial for your daily life. Rather, you can believe someone who is talented and skilled for the better future than you. It is not shameful at all to rely on others

Trip to Atami

Recently, I visited Atami.


Atami is located in Shizuoka prefecture. It is popular as a spa town. The climate is warm, and there are some palm trees along the seashore.


This pine tree is "Omiya-no-matsu." It is connected to "Konjiki-Yasha," an ancient tale of poor lovers.


At the top of a mountain, I could view the Sagami bay.


And nearby the Atami Castle, I found "Hiho-kan." It is a museum featuring erotic arts.


I also went to Hatsushima island. It was a small island. This shrine is "Ryujin-gu," located at the side of a main street in Hatsushima.


There was a rose garden nearby the hotel I stayed. Many flowers bloomed there.


Atami is rather a traditional spot for travelers. There are few exciting places. Young people tend not to visit there. But hot spring is good. I enjoyed staying.

Count of platelet may be a predictor of cancer

Recently, an amazing report about the screening of cancer was published in British Journal of General Practice.

According to the researchers at the University of Exeter, high amount of platelet in the blood is considerable to be a predictor of all kind of cancers. They examined approximately 50,000 people with age of over 40 in Britain, to find that participants with thrombocytosis; 11.6% of men and 6.2% of women, had a higher risk of cancer. Lung and colorectal cancers were more positively associated with raised platelets. The author of this paper claims that predictive value with counting platelet is as much as the manual screening for breast cancer, one of the most reliable way to find cancer.

The Guardian: High blood platelet count 'as good a cancer predictor as a lump in the breast'

If this hypothesis is correct, we must gain a strong weapon against cancer. Blood exam is now a very easy, cheap, and minimally invasive examination. If doctors in charge are a little more aware of interpreting the labo data, many people will be saved from fatally progressed cancer.


It is still unclear why increased platelets are relevant to a malignant growth. Perhaps, it is associated with the failure of the human immune system. Or, some types of malignant cells may cause a dysfunctional order to increase the production of platelets

Anyway, it is a quite interesting idea that platelet is associated with neoplasms. I will keep an eye to this progressive hypothesis for a while.

Is the tobacco filter rather harmful?

Researchers in Australia made a warning that a tobacco filter is no more useful to reduce the risk of cancer.


According to the paper recently published by the researchers at Curtin University, filter ventilation does not reduce tar yield. Instead, it slows the speed of consuming. Therefore, smokers are to absorb more tar with filter ventilation.

The Sydney Morning Herald: Modern cigarette filters increase the risk of lung cancer, study finds

They also examined the relationship between the prevalence rate of lung adenocarcinoma and smoking; the former is still rising. As I understand, smoking is not responsible for the onset of adenocarcinoma. Thus, this relationship is not necessary to be investigated for proving the harm of filter.

On the other hand, a large cohort study is needed to clarify the benefit or harm of using a filter. It is not adequate to say the filter raises the risk of cancer with examining past literature because there are no studies to have suspected this possibility.

Anyway, it is no doubt that tobacco is harmful to the human body. We should know there are no ways to attenuate the health risk of smoking as far as you smoke.

Firstborn theory still alive?

Do you believe the first born child is likely to succeed in business?

Firstborn children tend to be CEOs or politicians than other siblings by 30 percent, according to a new study by researchers at the University of Texas-Austin, and Sweden's Institute for Evaluation of Labour Market and Education Policy.

The Atlantic: Why First-Born Children Are Better Leaders

They consider that parents invest lots to their fist born child and that it may contribute to the success of them. Instead, later children are likely to live a freer life.


This hypothesis is at a glance persuasive. Many people feel that first born children are more independent and aggressive. However, there is a possibility of cognitive bias on the image of sibling order. When you notice I am the first child, you begin to identify me as so.

In addition, the so-called generational gap should be taken account. In a later era, it may be difficult to raise a company in some developed countries. Such environmental change is hardly adjustable with technical modification.

I believe family psychology is useful for better understanding of the client at the individual level. However, we should be cautious to generalize some principles to other families we do not know much.

Women in a deprived region become anxious than men

A recent large study showed that women were more likely to be anxious than men in a deprived region.


This study, published in British Medical Journal, targeted 21,000 UK people to investigate their anxiety level. As a result, 2.5% of the women were diagnosed with general anxiety disorder. And the wealth level of where they live was influential in women, not in men.

Independent: Poorer women far more affected by anxiety than men, study finds

The author suggested the fact that women were highly likely to be a single parent was related to this result. Also, lower wage in women seems to be associative.

On the other hand, genetic factors seem not to be mentioned in this article.  Women are likely to become anxious, generally speaking. Thus, they may be vulnerable to environmental factors to cause general anxiety disorder. I think this pathway is also not ignorable to discuss the high prevalence of anxiety in women in the deprived region.

Explosion attack at Ariana Grande concert in Manchester

Again, a terror attack occurred in England.


On May 22, 2017, an explosion emerged at the Ariana Grande concert in Manchester. It took at least 22 lives and injured more than 50 people.

Fox News: Ariana Grande concert explosion: 22 dead, 59 injured in 'terrorist incident'

It was 10:30 pm, immediately after the last number was finished. Ariana Grande herself was safe, according to her manager. The police are investigating this incident deeming as committed by suicidal bombers.

Nobody has claimed responsibility at the time I am writing this entry. But it is highly likely that some terrorists deliberately conducted this evil act.

In recent years, the number of terror reports is increasing in the UK. There are two possibilities behind this situation. First, border control is no more effective to prevent terrorists from entering the UK, albeit Heathrow airport was said to be the most strictly protected border. Second, some people in the UK are influenced by destructive ideology. In this case, it is also no use to excluding immigrants for protecting the cities.

There are many ideologies in the world. Each of them should be respected. However, I cannot accept the idea taking other's life by power, regardless of the reasons. I pray for the victims.

Edaravone is approved as a drug for ALS

Amyotrophic lateral sclerosis (ALS) is one of the deadly and painful diseases in the world. Patients with ALS experience gradual weakening of the muscles, leading to the failure of the respiratory system. As the intelligence and consciousness of the patients are not impaired, they have serious time for several years.


Recently, Food and Drug Administration of the US approved the second drug for ALS. Its name is edaravone.

Edaravone was developed by MT Pharma America, a subsidiary of Mitsubishi Tanabe Pharma Corporation, a famous Japanese pharmaceutical company.

The New York Times: A Second Drug Is Approved to Treat A.L.S.

In the human body, edaravone is bound to free radicals. Free radicals are considered to harm the human tissue seriously. Thus, edaravone has an effect of attenuating free radicals. Edaravone is also used for patients with an acute cerebral infarction, because it is believed that free radicals have a certain role in destroying brain cells.

In a placebo-controlled clinical trial conducted in Japan, participants with ALS who took edaravone were less likely to deteriorate their physical condition for six months. As ALS is a progressive disease, stopping the progress of shrinking muscle is a desirable outcome of this new drug.

Although this result is very promising, there is still barriers to overcome the suffering from ALS. It is impossible to reverse the progressed status of the muscle in the patient with the modern medicines.

On the other hand, free radical is one of the hot topics in the region of medical science. If edaravone has really a great effect of neutralizing free radicals, it will be utilized for several other diseases.

100% electric cars in India by 2030

The Indian government is planning to ban vehicles powered by petrol or diesel by 2030.

The energy minister intends to lower the cost of importing fuel, as well as alleviate the fatality caused by air pollution. Now, there are 2.3 million deaths due to air pollution estimated to occur every year in India.

Independent: India to make every single car electric by 2030 in bid to tackle pollution that kills millions

The introduction of electric cars is a trend in recent years. In some regions in Swiss, petrol cars are completely prohibited. Olso plans to make some areas even car-free.

My past entry: Oslo will partially be free from cars

However, these attempts are heard only in developed countries. Petrol vehicle is now a traditional way of transportation. It has rooted in our daily life. And they have become far less expensive than the past. Many people are willing to buy a car. Even in developed countries, an electric car is still a costly and inconvenient option.

Therefore, India's challenge seems unrealistic. Some comments on the article above suggest issues which need to be prioritized than electric cars.

On the other hand, if India accomplishes the withdrawal from petrol vehicles, it can have a strong impact. Many nations will follow it. And the behaviors of consumers will be altered. Car companies will have to change their strategy dramatically.

WannaCry storm

Recently, many reports of the damage caused by ransom ware, named WannaCry, attracted public attention.

Ransom ware is a kind of malware. It automatically encrypts the main data in the infected hard drive. Then, the attacker demands the ransom for recovering the data to the victim.


Some ransom ware were developed several years ago for the first time. Recently, hospitals were targeted to the cyber attack.

My past entry: Ransom-ware and Bitcoin in hospital

WannaCry utilizes a security hole in Microsoft Windows. In real, Microsoft released a patch to address this problem in this March. But some people had not adopted this update. It expanded the damage all around the world. Microsoft had to care Windows Vista, which had not been subject to the service by the provider, to prevent further damage.

And now, the number of victims are estimated as 200,000 in over 150 countries. National Health Service (NHS) in England was also victimized.

Independent: NHS cyber attack: Ransomware hits 200,000 victims in at least 150 countries, says Europol director
http://www.independent.co.uk/news/uk/crime/nhs-cyber-attack-wannacry-ransomware-victims-countries-europol-rob-wainwright-a7735001.html

One of the reasons for expanded damage is the dominance of Microsoft software. The Recent development of the internet enabled us to transfer astronomical amount of information immediately. Although its advantage is amazing, the magnitude of the risk by whom with malice is also gigantic.

On the other hand, utilization of ransom ware has a weak point as well as a real kidnapping. It is how to get the ransom. Modern cyber criminals tend to use Bitcoin to transfer money. Since Bitcoin is crypt currency, it seems anonymous. In real, however, all transaction of Bitcoin can be traced. And finally, the user has to exchange Bitcoin into real money. Stock exchanges, such as bankrupted Mt. Gox, are responsible for this transaction. At this stage, exchange always requests an identification of the user. Therefore, money laundering using Bitcoin is not so easy as imagined.

Indeed, British experts identified three Bitcoin addresses for the destination of the ransom. The total amount of Bitcoin was equivalent to only 20,000 USD.

The Guardian: Criminals behind cyber-attack have raised just $20,000, experts say

On the other hand, the price of Bitcoin is rapidly increasing. If the culprit does not exchange the Bitcoin he got as ransom into money, its value will be raised unintentionally.

Convenience and risk always coincide. We should be aware of the optimal balance of them. And when he draw the Bitcoin, he will be arrested.

Why healthy diet is difficult

Do you know the two essential things to maintain your health? Of course, they are regular exercise and proper diet.

Both are hardly accomplished. Especially, the latter is quite difficult for us to keep. Recent studies show you have to take five serves of vegetables and two serves of fruit every day. They seem a very large portion.

The Conversation: Food as medicine: why do we need to eat so many vegetables and what does a serve actually look like?

For taking adequate vegetables and fruits, the author of this article above recommends you to introduce some new types of items. Actually, a variation of food makes us motivated to try new menus.


However, the strongest barrier against varied meals is money. As mentioned in this article, poor people tend to take excessive carbohydrate. Vegetables and fruits are generally more costly than grain. Therefore, many people with financial problems are likely to omit vegetables and fruits for cutting expenditure. It takes their health in a longitudinal view.

Another reason is that vegetable is generally recognized as less delicious than grain and meat. Not a few people dislike taking vegetable. Even if you are fond of eating beef steak only with salt, you may need dressing to eat salad.

Deliciousness and energy are biologically associated. The human feel delicious when taking food with high energy. It is an instinct of the body.  As a result, most people in developed countries take excessive energy in the daily meal, which may contain little vegetable.

It is not easy to maintain a healthy diet even in wealthy people. We should be aware of the meaning of each meal we take. Acquiring proper dietary habit at the early age is helpful to continue it. Also, people with financial problems need support to achieve a healthy diet. Otherwise, they will get ill, resulting in the issue deteriorated.

Toxic coffee

There are some amount of people pursuing strong caffeine. Previously, I introduced an Australian cafe offering extremely dense coffee.

My past entry: An Australian café offers toxic amount of caffeine

And recently, a product with a similar concept is available also in the US. You can buy "Black Insomnia," as well as "Death Wish."

Amazon.com: Black Insomnia
Amazon.com: Death Wish

But are they safe for the human body? Probably, not. You should be cautious to its adverse effect especially you have a heart disease.


The limit of caffeine in a day you can take is said to 400mg. It is equivalent to four cups of regular coffee. In contrast, Death Wish contains 702 mg of caffeine in a cup.

The Atlantic: Drinking Four Cups of Coffee Is Probably Safe

Caffeine has several effects on the body. Taking much caffeine makes you hypertension. It will be a cause of myocardial infarction, at least theoretically. But, it is highly likely you are safe after taking this extreme coffee. The toxic effect of caffeine is too weak to have a fatal influence on your heart.

Nonetheless, there is a case of fatality due to excessive taking caffeine in Japan recently reported. I never recommend you to take caffeine excessively.

Some people pursues stimulus. It is a kind of addiction. The addictive tendency is often elevated with chronic exposure. If you are indulged in coffee, take a break for a while.

Risk of death in several activities

All of us will die for some reasons. It is an absolute fact. But, it is not sure what will kill you.

Most people in developed countries are killed by some disease. Malignant neoplasm is one of the main causes of death. In some countries, especially with a lower standard of medicines, infectious diseases are more dominant as a reason of death.


In contrast, there are relatively a few people die in an accident. Do you know someone around you who were killed in a car accident? Or, you may be afraid of the crash of an airplane. In real, it is not realistic to be concerned about such immature death. Statistics shows there is merely one per a million risk of fatality within 40,000 km of the aero trip. The probability an airplane takes your life is less than a marathon.

The Conversation: What’s most likely to kill you? Measuring how deadly our daily activities are

This kind of comparison attracts public attention. But it is because most people cannot estimate the risk of each activity precisely. We are fearful to be attacked by a shark. In real, however, kangaroo is dangerous as same as a shark.

We have cognitive biases. An apparent danger brings a fearful emotion to our mind. Then, we tend to overestimate the likelihood of the incident. An impressive episode also draws our emotional reaction. As a result, we are prepared excessively to a rare undesirable event. The enhanced security checking in the US after the 9.11 terror attack is a good example.

Our fear has protected us from several terrors in nature. But, it is not rational to rely on our instinct in considering the risk control. Precise estimation and deliberate discussion are needed in managing the risks.

Benefit of sadness: is it true?

As all we are humans, we experience several types of emotion every day. Some of them are comfortable: joy, loveliness, excitement, and happiness. In contrast, we are occasionally attacked by bad emotions.


Negative emotions such as sadness, fear, anger, and pain are unwelcome. But they are unavoidable in our life. In recent years, some researchers are eager to evaluate these emotions focusing their positive effects.

The Conversation: Why bad moods are good for you: the surprising benefits of sadness

According to the author of this article above, people in sad mood often have good performance in anticipating and communicating in some situations. I have heard a similar anecdote. Some people were encouraged to play a game. The result of each game was determined completely by chance. Participants in a depressive state could recognize that their effort to win the game was no use. But participants in normal mood misunderstood that they had won the game by their skills.

Thus, negative emotions often help us to make a deliberate decision. In contrast, people in an elevated mood are likely to make a bold decision. It sometimes results in a miserable failure. Many successful executives call themselves as a timid administrator.

As well as sadness, anger and fear are also productive in some situations. If your child is in danger, you should become angry to save your child's life with any compensation, according to the author of this book below.

Amazon.com: The Upside of Your Dark Side

Considering these ideas, negative emotions are neither to be avoided, nor to be ignored. The author criticizes the current tendency of wanting to eliminate any negative emotions in the US.

Their claim seems rational. For example, you may feel extremely sad after the death of your sweetheart. But, how do you feel if your doctor recommends you to take antidepressants then? Are you happy if the pill erases your sadness completely?

The answer, however, depends on the magnitude or your grief. Some people commit suicide after a sad event. Even if I understand the agony of the person, I never accept the decision of taking his or her life.

In my opinion, there is a difference between natural sadness and pathological sadness. And the latter should be subjected to medical care. It is often difficult to distinguish them. Therefore, we should be cautious to deem the emotion as unhealthy. In real, people consulting a counselor are treated as a client. So, we provide medical care for them.

Longer imprisonment would be no good

Japan has several advantages as a nation. On the other hand, I believe there are some customs in Japan. For example, criminal justice systems in Japan is outdated.

In a historical point of view, Japan has strengthened the degree of punishment for crimes repeatedly. In recent years, a person who caused a traffic accident while recognizing that he or she had a risk, (e.g. some physical or mental diseases) was to be accused of "vehicular homicide." Thus, people who have epilepsy or diabetes are likely to be punished harshly when causing a car crash.


As well, the punishment for juvenile crimes is gradually enhanced.

It is well known that longer imprisonment is unlikely to prevent further crimes by the perpetrator. Also, it is doubtful to make other people stop committing crimes. At least in the level of academic research, harsh punishment is no longer useful for public safety at all.

In addition, imprisonment is costly.  In Australia, 1,000 USD per year is needed for keeping a criminal in the prison. The situation is similar in Japan.

The Conversation: Mandatory minimum sentences and populist criminal justice policy do not work – here’s why

Also in Australia, dilation of the mandatory term of imprisonment seems to be a recent trend. The main reason may be the rise of populism. Excluding criminals from our society sounds good, because no one wants to be victimized.

However, it would not be a solution in a longitudinal view. People who were incarcerated will be released some day. If they have not learned the way to be reintegrated into the community, they will have no choice but re-offend. In real, longer imprisonment gets rid of the power of living from detainees.

In Japan, 90% of the people support the capital punishment. It is shameful to know my neighbors will never accept people with offending history. It represents the tradition in Japan not permitting a failure.

Itching, and more, are other senses than our five senses

You may have heard the words "sixth sense," meaning an extraordinary power. Thus, humans have only five kinds of sense; sight, hearing, touch, taste, and smell.

But Chris Eccleston, a British psychologist, says that there are more than five senses we have. And he claims that several senses are paid attention for better medical treatment.

Sydney Morning Herald: Forget the sixth sense. Meet the 10 neglected senses that could help the way we treat pain

According to him, senses other than traditional five are motion, balance, pain, pressure, fatigue, breathing, temperature, appetite, expulsion, and itch.


This explanation sounds rational. All we can feel and understand these senses. Indeed, it has been proven that the receptor of pressure is different from the receptor of touch. For example, you get anesthetized before your tooth pulled out. You may feel the sense the presence of your sick tooth being lost, despite the absence of any pain.

Prof. Eccleston also commented that itch is contagious. I am doubtful to his idea, however. I am not sure that there are some clinical trials to examine this hypothesis. If the itch is infectious, we will feel itch even if you cannot see the person in front of you itching his skin.

I guess we imagine the itching sense when confronting a person suffering from itch. Thus, it is no other than empathy. As well, we feel pain when seeing a man with a painful face.

Nevertheless, we are now ready to think more deeply about our senses. In the near future, "sixth sense" will be no more available, perhaps.

Rakuten Asset Building Festival 2017

Yesterday, I attended a seminar produced by Rakuten Securities. Its name is "Rakuten Asset Building Festival 2017."

Rakuten is a famous company which was originally developed as e-commerce. Now Rakuten is a gigantic company so that it is often compared with Amazon in Japan. In recent years, Rakuten began some other businesses such as Rakuten Securities and Rakuten Golden Eagles as a professional baseball team.

There were over a thousand people listening to the seminar. The theme was personal asset building.


In Japan, many people do not trust the scheme of the public pension. Aging is so serious in Japan that people over 65 are over a third of the population. It means that young generation needs to support many elders. It is hardly believable the public pension for elders will be sustainable in the future.

In the seminar, a couple of guests were invited to the talking session.  They were Kintaro and Amemiya; both are famous comedians.


Some Japanese comedians earn a large amount of money if they become popular. Most of them know that their reputation will not last forever. But they are not familiar with managing their estate. Indeed, some of them experience bankrupt with deceived by someone.

I learned some important issues yesterday. Asset building is not a complicated matter. But some people misunderstand it. I will reconsider the portfolio of my resources.

Bubbling Bitcoin

Recently, crypt currency became a hot topic again. The price of Bitcoin jumped up in this month, and now has overcome the highest range ever before, reaching 1,800 USD.


Other crypt currencies are also rocketing.


One of the reasons is that "segwit," a new scheme for solution of the scalability issue, was going to be equipped in some currencies. This topic had been discussed for these some years.

Also, instability of political situation in some nations may be influential to the value of crypt currency.

However, I am doubtful to justify the current price of crypt currencies. The structure around Bitcoin is still vulnelable. In the near future, the prices will be damaged by some trust risks, I guess.

Trip to Izumo and Tottori

Recently, I visited Shimane and Tottori prefecture, an western region in Japan.

Izumo is called as a land of Gods. In ancient Japan, it is said that all Gods of Japan are gathered to Izumo in October. October is also called "Kannna-zuki" [a month without gods] in a traditional term in Japan, except Izumo area. In contrast, Izumo people call October as Kami-ari-zuki [a month with gods].

Izumo Oyashiro is a famous shrine. It was very big and so solemn that I could not take a photo there.


And there are some famous Japanese traditional parks. They were also beautiful.

This is Yushien.


A large numbers of peonies were planted there.


This is Adachi Museum of Art. It equips a gigantic Japanese park.


I also visited Tottori sand dunes. There are no deserts in Japan. Therefore, I enjoyed this place as I entered a dune for the first time.


I completely enjoyed this journey.
