This is a famous Taoist saying, and it is also the first time that the concept of immortality has appeared in people's field of vision. Since ancient times, many people have been addicted to pursuing this illusory thing. There are descriptions of immortality in various religious classics, and even many people begin to believe in religion and practice themselves just for "immortality". However, in the field of science, the real method of immortality has not been discovered, so it is actually difficult or even impossible for people to pursue immortality. Even so, there are still many people who are crazy about it.

There was once a rich man in the United States who wanted to preserve his body by freezing himself, so that he could be resurrected in the future. So the rich man got a chance to be frozen by virtue of his assets, and this freezing was 53 years. Did his wish come true?

The name of this rich man is James Bedford. James is a Kochi group. He works as a professor of psychology in a school in California, USA. He is respected and well paid in this position, so James has become a very famous rich man.

James is not like an ordinary professor. He has a certain interest in all kinds of sports, so James is very strong. Even after he retired, he began various exploration activities. From the African savannah to the Amazon jungle, James always came back alive, which also depends on James' emphasis on healthy body. It can also be seen that James is a very adventurous person and is not afraid of anything.

In this case, James accidentally came into contact with the experiment of cryonics technology. Cryopreservation technology has been studied by scientists for a long time, with the purpose of preserving the human body at extremely low temperature so as to revive it when the technology is developed in the future, but at that time everything was unknown and everything was still being explored. Many science fiction writers are very fond of this technology, and they often describe it in their literary works. For example, in Interstellar, astronauts can live for a long time without nutrition intake by freezing themselves in space, and because they are in a dormant state, they have no knowledge of everything outside. It sounds really strange and interesting when a person wakes up for a long time.

At that time, this experiment also attracted James. When they recruited volunteers, James signed up for this experiment despite the dissuasion of other relatives and friends. James has always had a keen interest in such emerging affairs and encouraged its development. At the same time, there is another reason that James has cancer. Although James attaches great importance to his health and often exercises, the disease is ruthless and the cloud of illness still hangs over this man.

James is a man who cherishes his life. Soon he thought of the consent form signed at the beginning. At this time, James' family stopped discouraging him. In 1967, James died of lung failure. Because the family contacted the institution of cryonics experiment in advance, after James lost his vital signs, the laboratory staff took James' body away and frozen it.

The duration of this project is 5 years, and James should be awakened in 217. In 217, people all over the world cast their eyes on the experiment here, expecting the results.

Before James began to freeze, the laboratory staff injected a heparin for James according to the theoretical knowledge. The function of this heparin is to prevent James' blood from clotting. After that, all the blood in his body should be pumped out, and antifreeze liquid should be used instead of it to complete the whole body circulation.

This antifreeze liquid is also called cryoprotectant. The scientific name is DMSO, which has a very high production cost, but this is the first time that this institution has injected human body, and it is not clear whether it can play a practical role. The staff in the laboratory stuck the needle into James' artery, then injected the cryoprotectant. After the injection was completed, other steps were started, including pressing James' chest and putting James on a ventilator.

After all the preparations were finished, the staff finally put James into the sleeping bag. The material of this sleeping bag is polyester. In fact, this material is often used in our daily life, but no one thought of applying it here. In this way, James is like being put into a big transparent plastic bag, and the outside world can clearly observe all kinds of situations of James.

All these preparations have their own scientific basis. First of all, what scientists want is to make the "blood" of the human body still work normally in this environment. The function of this artificial "blood" is very powerful. Finally, James is sealed to prevent air from entering, which will destroy the unique environment in the freezer, and at the same time, it can prevent bacteria or other microorganisms from breeding in the freezer, so as to ensure that the freezing effect will not be affected.

James was put into the freezer to reduce the temperature by dry ice, which was a very perfect plan at the theoretical research level at that time, because most people thought that this kind of refrigeration was through power supply, but the danger of using power supply was too high, and it was also necessary to consider that if there was a sudden power failure, the temperature of the freezer would soon rise, which made it difficult to complete the experiment. Choosing dry ice will put an end to this situation, and this pot-shaped refrigerator will always keep a constant temperature.

Then, the treated James' body is sent to the frozen warehouse set up by this scientific research institution in Arizona to start freezing. Before freezing, James' body should be moved again, from the place where there is only dry ice to the professional setting in the frozen warehouse. Even if the temperature is constant at MINUS 149 degrees Celsius, the liquid nitrogen tank is better than the dry ice tank.

James's body began to sleep there, just like James's previous dream of coming back to life. All the staff here are devoted to studying how to realize his dream. In 1991, James's body was moved again, and moved from the liquid nitrogen tank to another more scientific freezer, which also reflected the rapid changes in science in these years.

At the same time, more and more people accepted this technology and volunteered to be the experimenters of this technology. Volunteers from all over the world came here one after another to accept the freezing technology, and there were more than 4 people. They all believed that this technology could bring them new life like James, so they did not hesitate.

This project has been going on for 5 years. In 217, James should see the light of day again, but in fact, by that year, James has not been awakened, because science and technology have not reached that level. Scientists in the United States thought it was very simple to break through this technology decades ago, but it took 5 years to make a real breakthrough, so they can only face failure if they wake up these sleepers rashly. James and more than 4 other volunteers can only sleep there quietly, and maybe they will be suddenly woken up after many years.
