There are more than 150 patients at the “Alcor Life Extension Foundation.” Each had their body frozen cryonically shortly after death in the hopes that one day, medical science will find a cure for what killed them, and they can be revived and healed. It's a scientifically dubious idea, but some people are willing to pay a lot of money in the hopes that one day they can come back for a long and healthy life. Iacopo Luzi has the story.
