In the office, Chen Changan was writing quickly in front of a notebook.

Human body freezing and artificial hibernation seem to be the same, but in fact they have two completely different meanings.

Human body freezing technology, as the name suggests, is to preserve human bodies or animals at extremely low temperatures, usually at low temperatures below minus 196 degrees Celsius, and hope to resurrect and treat them in the future through advanced medical technology.

This is a fantasy technology, and this idea first appeared in the science fiction novel "Strange Stories" published by science fiction novel Neil Jones in 1931.

And at present, in the real world, there are really companies doing this!

The most well-known human body freezing company is currently in the United States, called the Arco Life Continuation Foundation.

The foundation has frozen 160 corpses, including celebrities, the world-renowned ones!

And there are more than 2,000 people who have signed up for the foundation's human freezing project.

And how does this life-continuing foundation specifically freeze the human body?

The whole process is like this: When a person is declared legally dead, the doctor will stabilize the body and provide oxygen and blood to the brain; then wrap the body with ice and inject anticoagulant to prevent the blood from coagulation during transport to the human body's freezing facility.

However, there is a large amount of liquid in the human body, and these liquids will start to freeze slowly when they are below zero. Ice crystals will stab the cells and damage the tissue. How to solve this problem?

Human cryogenists will drain all the water and blood in the human body and replace it with antifreeze to turn the human body into antifreeze to prevent organs or cells from being damaged by ice crystals during the freezing process.

After this series is completed, the human body will be stored in a liquid nitrogen metal bucket with a temperature of -196℃ and will be kept. At this temperature, the cells will stop all physiological activities.

Some people in China do this. The editor of the famous novel "The Three-Body Problem" freezes the human body, but she is even more extreme, and she only freezes her head!

However, it is worth noting that although these people have been frozen, there is currently no way for the scientific community to thaw and resurrect them!

The Alco Life Continuation Foundation also hopes to wait until the future is highly developed medicine, and scientists have the ability to revive them and treat their terminal illnesses.

The world's first human body refrigeration was in 1967. James Bedford, a psychology professor in California, chose to freeze himself after suffering from kidney cancer, hoping to thaw and cure himself through future technology.

He left a hundred thousand dollars in his will, signed a 50-year freezing volunteer, turning himself into the first frozen man, and in 1991 he was transferred to a more advanced metal can.

But in 2017, the Frozen Company announced that it would thaw Bedford in thaw.

It is obvious that Mr. Bedford was not resurrected, but a body that had been frozen for fifty years, not Captain America.

However, even so, the technology has almost become a gamble for the rich.

Now all countries around the world have their own human body freezing programs.

The fees range from US$10,000, US$28,000, US$155,000 and US$200,000 respectively. The fees vary depending on the company, service, country or region.

But to be honest, this kind of human body freezing can almost be said to be unsuccessful.

There is no experiment now that the cells can still be preserved after a long period of freezing.

There are no examples of freezing successfully and thawing.

Even a large number of scientists believe that human body freezing technology is simply an impossible technology, a technology for making modern mummies!

If scientists are just guessing, then Chen Changan can give an answer directly.

This type of human body freezing technology is simply impossible to succeed.

Everyone is dead, how can you freeze?

Even if you choose to freeze when your life is dying, when you are really frozen to -196℃, you are already dead.

During the freezing process, a large number of cells will die, and the brain stops all activities and completely dies.

You should know that the human brain is active all the time. Even when sleeping, the brain waves are very active. The transmission of brain cells' signals is not disorderly. Only ordered signals can form consciousness. Once the human brain stops moving, it means death.

Let’s take a step back, even if there is really a way to revive a corpse in the future, the signal transmission between brain cells after revival is still chaotic, that is, after revival, it cannot have the ability to think normally, and it is just a vegetable!

Resurrection of a completely dead person? This is simply a fantasy. At least in the world of science, it is impossible to achieve, unless you are a cultivator, then I didn't say it.

The only purpose of this human body freezing technology is to extract some cells from frozen corpses countless years later and clone a clone with exactly the same genes. However, this clone has no memory. From a genetic point of view, he can be considered another you.

But in fact, he is not you, he is just a person who looks exactly like you. If you are frozen, you are dead and can no longer die.

Human body freezing technology is a technology that has no medical value at all!

However, the infeasible human body freezing technology does not mean that humans cannot delay the passage of life and may lie in a long time to wait for the possibility of waking up in the future.

What can really do this is artificial hibernation technology!

Many animals hibernate naturally. When hibernation, cold, hunger, and disease are helpless to them.

During hibernation, animals can reduce metabolic activities by 98% due to their reduced body temperature, resulting in a "sleeping" state of the entire physiological activity, that is, the life process is relatively extended.

If you continue to hibernate for a hundred years, but your body is actually only aging for two years, nature is so magical!

Therefore, many animals that can hibernate in nature live a long life, especially compared with animals that cannot hibernate, they are simply considered immortal species.

But humans do not have the characteristic of hibernation.

Therefore, under the conditions of hibernation, technology to resist the harsh environment, incursions and even prolong lifespans, has emerged.

Chen Changan mastered a method of using drug-induced induction to create conditions for artificial hibernation!

In the case of artificial hibernation, the body temperature will remain between 34℃ and 35℃, which is slightly lower than the normal body temperature. However, all organs in the body will not stop working completely, but will use an extremely low metabolic activity to ensure the body's minimum survival needs.

Under this artificial hibernation condition, the heart only beats once every few days, and all physiological activities are very slow. After several stops, including brain cells, they also fall into a deep sleep, and the activity level of brain waves is also reduced to the lowest level!

Moreover, a hibernation can last up to thirty years at most!

After stopping hibernation and taking medication, the body temperature of hibernation patients will be heated up. When the body temperature returns to normal temperature, the hibernation person will wake up naturally.

After that, you only need to have normal activity for two months before you can hibernate the next time!

This is the real hibernation technology!
