Rich people want to be young again.

"Why do you want to live forever? Yuan is the first class. " Throughout the ages, immortality has been a wish of people. From the practice of civilians to the alchemy of emperors, almost everyone wants to enjoy life forever. For example, after the unification of the six countries, Ying Zheng, the first Qin Emperor, was in a high position, and his desire for immortality became stronger and stronger. In addition to ordering Taoist priests to refine Dan medicine, he also ordered people to look around for Dan medicine. According to historical records, in 2 19 BC, Qin Shihuang sailed around Shandong Peninsula for three months, hoping to get the elixir from the immortals in Penglai, Yingzhou and abbot, but failed to do so. However, after the unification of the six countries, Qin died in 12, and he himself did not live to be 50 years old.

This shows that human beings are crazy about immortality! Even in modern times, with the development of science and technology, it is clear that death is a law that human beings can't jump away, but I still hope to live as long as possible. And some scientists want to accomplish this wish through technology. There are also some rich people who also want to use money to buy opportunities for immortality or rebirth. For example, there is a rich man in America. 56 years old, lived to 120 years old, spent millions, and changed the blood of 18 years old. What was the result?

Peter teale, a rich man who wants to change his blood and achieve a short life, is the author of From 0 to 1, a mentor of Stanford University, a famous investor in Silicon Valley and the founder of PayPal. He has made brilliant achievements in his life. In his old age, he also had the wish of immortality, but as we all know, including today's technology, he can't fulfill this dream of immortality. To this end, he first strives to live to be 120 years old for himself, hoping to gain a fresh life by changing the blood of young people and achieve the goal of short life. In addition, he also booked a cryonics plan in advance, hoping that he would be frozen after his death, and one day he could be resurrected when the related medical technology reached a certain level.

Peter thiel seems to be rampant, but in fact many people have this idea, including some scientists. For example, James Bedford, the first freezer in the world, was refrigerated in June 1967. Although he has been refrigerated for 53 years, he has not been resurrected. As long as his body is well preserved, it is hard to say that he will really be resurrected one day with the infinite power of science and technology. And now related technologies are still being developed from time to time. So, can Peter Tiller's wish to achieve reverse growth through blood come true?

Therefore, Professor Clive McCay, a biochemist, used 1 half-month-old mice and 16-month-old mice to stop blood circulation at 1959. Through experimental research, it is found that their average physiological age is half younger. Why can a change of blood reach a certain young state? From June, 2065438 to June, 2009, the University of Washington found that this is because the eNAMPT enzyme in blood has been improved, that is to say, if this enzyme is improved, maybe human beings can really complete the reverse growth.

In addition, the researchers injected EV containing eNAMPT purified from the plasma of young mice into 26-month-old mice. The experimental results show that the maximum life span of aged mice is extended to 65438 05.8%, and the appearance is obviously improved. After further research, eNAMPT enzyme was increased in school, which improved the ability of glycoside synthesis and β -nicotinamide in old mice. Under normal growth conditions, these two substances will gradually decrease with age in human body, and their degree and content are related to aging. Simply put, the metabolism of cells is inseparable from them.

From the above experimental data, it can be seen that the desire to achieve "reverse growth" through blood exchange is still very likely to be completed. Of course, although some related achievements have been made in biological experiments, it is not certain that human beings can be rejuvenated in this way. This is a complex "biological decryption" process, which needs more and more powerful proof. For example, on 20 16, Ambrosia Company of the United States was urgently stopped by the FDA due to safety problems such as rejection, but this technology of trying to reverse growth through blood exchange is still under discussion. Whether Peter Tiller can live to 120 years old through blood exchange as he wishes depends on his future answer.

As for another wish of mankind-rebirth, is it possible to complete it? Judging from today's science and technology, there are still many problems, which are still difficult and far away. For example, Du Hong, the first freezer in China, was frozen at 20 15, and it is planned to be resurrected in 2065, but no one can guarantee whether it can be resurrected as planned.

Where you will go is the biggest problem in the world. If only we could deal with this heavy problem through science and technology in the future. However, if this wish of mankind is really realized, there will be rebellion and nature in practice, and at the same time there will be some potential negative results. After all, technology is a double-edged sword. If you want to get some benefits, you always have to pay other costs. But whether you can live forever or not, isn't the average life expectancy of human beings getting longer and longer?
