In the desert climate of Scottsdale, Arizona, rest 147 brains and bodies, all frozen in liquid nitrogen with the goal of being revived one day.
It's not science fiction — to some it might not even be science — yet thousands of people around the world have put their trust, lives and fortunes into the promise of cryonics, the practice of preserving a body with antifreeze shortly after death in hopes future medicine might be able to bring the deceased back.
"If you think back half a century or so, if somebody stopped breathing and their heart stopped beating we would've checked them and said they're dead," said Max More, CEO of the Scottsdale-based Alcor.
