Cryonics facilities subscribe to the belief that in the future, medical technology will have advanced enough to "resurrect" people who are legally dead in today's terms. One famous cryonics company, Alcor, keeps tabs on its members so that it can begin the preservation process as soon as they pass. They replace blood and bodily fluids with an antifreeze solution, then cool the body to around -320 degrees Fahrenheit before transferring it to a container of liquid nitrogen. (The body is wrapped in a sleeping bag so that the nitrogen doesn't damage the skin.)
