In many science fiction novels, cryonics technology is indispensable, when someone has a disease that cannot be cured by medicine now, they will choose to freeze themselves, and then wait until after scientific and technological progress, thaw and resurrect, and can still maintain their young face, but this is only an idea. Although there are examples of cryonics all over the world, the final result is unknown to everyone, and no one knows whether cryonics will become a life-sustaining science and technology.
The United States has long used cryonics technology commercially, so some people still freeze themselves, and the cost per transaction is about 1.5 million. At present, the refrigeration technology in the United States has more than 100 customers, and until now no one has made a bad review, after all, customers now have no way to tell their current experience, and now most of the common people are put into metal jars, and then frozen by 180 degrees of liquid nitrogen.
In 1976, a psychologist in the United States became the first frozen person, but after 50 years, the American freezing company directly thawed him because his relatives did not continue to pay the fee, but then there was no result, so many people began to suspect that cryonics technology may be a scam, relying on the current science and technology can not be frozen people to resurrect.
In fact, theoretically, it is possible that the human body can be resurrected after freezing, after all, in nature, there are cases of frozen organisms resurrecting after thawing. For example, a forest frog can secrete a substance to dehydrate its cells, and then freeze and choose a warm season to revive. After research, scientists have found that when the organism is slowly frozen, it will cause the organism to die, but too fast will also make the organism die, so it is important to master the speed of freezing.
The current freezing technology is to wait for the patient to die, put the patient into ice water, and inject anticoagulants into the blood, and after the blood and water in the body are discharged, the antifreeze will be injected, and then according to the calculated speed, frozen at minus 196 degrees Celsius, and then loaded into an insulated bag containing nitrogen, put into a liquid nitrogen metal container for preservation, waiting for technology to resurrect the person again, but as for the time of resurrection, it is still an unknown.
