Life after death?

What is Cryonics?

Cryonics is the act of freezing a human body, shortly after they are declared legally dead with the intent of being able to be resuscitated when the technology is available. Cryonics is expensive, with services ranging in the hundreds of thousands of dollars.


To be preserved for a long duration, the body temperature must be decreased to 77.15 Kelvin, or the boiling point of liquid nitrogen.

According to law in the United States, cryonic procedures before being declared legally dead is murder or assisted suicide. Because of this, cryonic procedures must be done just minutes after death, to preserve the brain and body cells.

Cryonic procedures involve injecting the patient with a cryoprotectant, to prevent damage to body cells.
