But does current evidence suggest that the gamble will pay off or does cryonics simply give desperate people false hope dressed up in the language of science? There are two advances that make cryonics a little less far-fetched that it once was. Vitrification prevents this by replacing the blood with a mixture of antifreeze-like chemicals and an organ preservation solution. However, even vitrifying larger structures, such as human kidneys for transplantation, has never been done clinically and remains some way off. From a purely scientific perspective, your money is probably better spent while you are still alive.
