G-g-g-g-ghost!? Trucker shares chilling footage of apparition
A man and his family have signed up to preserve their bodies in liquid nitrogen tanks, in hopes they'll wake up in the future.
Dennis James Kowalski, 54, told Insider he first learnt about cryonics as a kid in the 70s. Kowalski was inspired by the TV segment and went on to carry out his own research for the future.
Cryonics "is the practice of preserving humans and animals at cryogenic temperatures in the hope that future science can restore them to a healthy living condition as well as rejuvenate them," according to the National Library of Medicine. "At present cryonics can only be performed after pronouncement of legal death of the cryonics subject."
Now, the head of the Cryonics Institute, Kowalski's "gut instinct" believes that in 100 years we'll have the technology to revive someone from the dead.
"But nobody knows the future, and it's impossible to know for sure," he wrote. "You've got nothing to lose by preserving your body after death but potentially everything to gain."
