One way in which you could give yourself the opportunity to live even after death is with cryonic suspension. It may have been able to bring back Austin Powers after 30 years of suspension, but beyond the world of science fiction, the practicalities of cryonics remain a mystery. Right now we have the technology to cryogenically preserve a human body, but remain clueless on how to revive them when the time is right. It’s the belief that humankind will one day find a way to successfully thaw patients and treat whatever illnesses led to their death. The world leader in cryonics, Alcor, currently has 181 patients and has been storing humans for 49 years, including the company’s founder, Fred Chamberlain.
The process of preserving a human body through cryonics involves replacing the water content of a body with a chemical cryoprotectant, which works like antifreeze. This is to prevent ice crystals forming during freezing and irreversibly damaging the body. Once filled with cryoprotectants, the body will eventually be placed into a tank of liquid nitrogen at around -196 degrees Celsius, where it will be stored.
