Will Cryosleep ever be possible?
There are many instances of animal and human bodies found in the ice, frozen, yet preserved and not damaged by the extreme temperature. This makes the concept of a ‘cryosleep’ sound doable. Although the concept has never become mainstream, around six companies were established in the 1970s to use the technology.

What is cryogenic sleep?
Here’s how cryogenics works: Bodies are preserved through the process of vitrification. An antifreeze agent is added, replacing water in the cells. The tissue is then cooled to -220 degrees Fahrenheit, but instead of crystallizing into ice, the chemicals clump together and become solid, molecularly similar to glass.
Why can’t humans hibernate?
