Can You Cryogenically Freeze Your Body and Come Back to Life?

When you die, there are a lot of things you can do with your dead body--embalm it, cremate it, donate it to science (the list goes on…), but some people will choose to have their dead bodies, or body parts, frozen until the technology of the future has (hopefully) advanced enough to bring them back to life. This week on Reactions, we break down the chemistry of cryogenic freezing and if it’s realistic to think we could ever reanimate a frozen corpse.
