Here's an early '90s clip of the Alcor Life Extension Foundation, a cryonics business in Arizona. This is clip 2 of 6. 

Shown are Alcor workers receiving a recently deceased body at their facility and preparing to perform cryonics on this same deceased body. Cryonics, in short, is the process of preserving a body under cold conditions with the hope of reviving the body in the future.
