The first point of the first chapter of a brief history of the future is that modern people suffer from cancer and heart disease and die more than ancient people because the ancients lived too short. Secondly, terrorism is simply a weak policy adopted by those who do not have real power. In the pursuit of health, happiness and strength, human beings slowly change their own traits, so that the traits change one after another, until human beings are no longer human.

Recently, I have been watching Yuval Harari's A Brief History of the Future, which has many refreshing views and I would like to share my feelings about it.

<h1 class= "pgc-h-arrow-right" > the first point, modern people suffer from cancer, heart disease and die more than ancient people is actually because the ancients lived too short. </h1>

In fact, many people see these data at the first glance, they will take it for granted that the modern material conditions have become better, and the ingestion of harmful components to the body has become more, so it has led to the above situation. But Harari wrote in this book that "cancer and heart disease are certainly not new diseases, they have existed since ancient times, but the average life expectancy of the ancients is short, and it is too late to die from these two diseases." This reminds me of survivor bias, which is defined on Baidu as follows: Survivorship bias, also translated as survivor bias or survivor bias, is a common logical fallacy ("fallacy" instead of "bias"), which refers to seeing only the results produced by some kind of screening, without realizing the screening process, and therefore ignoring the key information that is filtered out. I remember that one of the more typical examples was the college entrance examination essay questions of a certain year. It was probably about experts discussing which parts of the aircraft should be reinforced to better suit the needs of war. Most people think that the thinnest part of the fuselage that is attacked by shrapnel should be reinforced, but some people have put forward a different view, he believes that the thick part should be reinforced, because once hit here, the aircraft can not return to the sea.

For the vast state apparatus, terrorism is clearly extremely weak. Even according to statistics, people who die from terrorism are only a few percent of deaths from obesity and other related diseases. So why on earth has it been able to have such a big impact? There is a very vivid example in the book. Terrorists are like a fly that wants to make a big fuss about a porcelain shop. It was so weak that it took a cow and burrowed into his ear and buzzed, making the cow mad with fear and anger, thus destroying the whole porcelain shop. It's like giving my spiritual world a collapse and reconstruction, and looking back and thinking about it, it seems like he said it.

<h1 class= "pgc-h-arrow-right" > in the pursuit of health, happiness and strength, human beings slowly change their traits, so that traits change one after another, until humans are no longer human. </h1>

This is similar to the ship of Theseus, which was a question posed by Plutarch in the 1st century AD, about a ship that could sail at sea for a long time, and each time it had to be replaced with a new ship part, until finally the entire ship part was replaced. So is the current ship still the original ship? This is a question worth pondering, when all our traits are changed, are people still human? Am I still the same person I was? Are you still not the same person you were?
