Around 500 people worldwide have chosen cryonic preservation, a process in which the human body—or sometimes just the brain—is frozen immediately after legal death. Stored at –196°C in liquid nitrogen, the goal is to halt biological decay until future medical science can reverse the damage that caused death. Cryonics does not claim revival is possible today. Instead, it is a long-term gamble on advances in nanotechnology, regenerative medicine, and neuroscience. Supporters argue that preserving
