Who has had their body frozen?
Until the day he died, in 2011, Robert Ettinger hoped humanity would figure out a way to cheat death. Today, his body is stored in a cryonic vessel filled with liquid nitrogen and frozen to –196 degrees Celsius.
Has anyone been frozen and brought back to life?
Well, for one, no one has been cryogenically frozen and revived yet. Though we’ve had some luck with animals. One study revived a tardigrade, also known as a water bear, that had been frozen for more than 30 years.

It is possible to confirm or rule out whether freezing and thawing has occurred by testing the activity of the enzyme short-chain 3-hydroxyacyl-CoA dehydrogenase (SCHAD).
How do you die from liquid nitrogen?
Liquid nitrogen is not poisonous but can expand up to 695 times in volume when it vaporizes and has no warning properties such as odor or color. If this happens, it can displace oxygen and cause unconsciousness or even death.
