Cryonics, the practice of preserving human bodies at extremely low temperatures, was first proposed by Robert Ettinger in 1962. The process aims to halt metabolic functions and prevent cell damage by using vitrification, which avoids ice crystal formation. The body is then preserved in liquid nitrogen at -196°C, with the hope that future medical advancements might revive the person and cure the cause of death.

James Bedford was the first person to undergo cryogenic preservation in 1967, and since then, over 5,500 people, including wealthy individuals, have signed up for the procedure. The appeal of cryonics lies in the belief that future breakthroughs in nanotechnology and regenerative medicine could make revival possible. However, the practice remains unproven, and there is no scientific evidence that it will ever work.

Notable figures, like baseball legend Ted Williams, have also been cryonically preserved, raising ethical and legal concerns. While the future of cryonics is uncertain, it reflects humanity’s ongoing desire to conquer death and achieve immortality.
