Why I am a cryonicistLike most people who aren't depressed, I don't want to die. Unlike most of those people, I think there's something I can do about it. If I am reduced to an inoperative condition by disease or age or being hit by a truck or some such, I want to be frozen until whatever went wrong can be fixed.
I know that if I'm burnt to a crisp in a fire (like if I'm cremated), or if I'm completely decayed and eaten (like if I'm buried), or if my brain is otherwise destroyed, there won't be any Me to freeze. But as long there's a Me, I want to live. Certainly it's possible that cryonics won't accomplish that, but it's the best last resort that's available.
I'd much prefer to last until science solves the problems of aging and disease, and cryonics becomes less necessary (as I've heard said, "Cryonics is the second-worst thing that can happen to you."). I even think that might happen in the next fifty years. But accidents can happen at any time, and I want to be as prepared as I can be. The legal paperwork for cryonics can't be completed by someone in a coma or worse.
How I put my money where my mouth isI'm a member of the Alcor Life Extension Foundation. I pay $230/year for a term life insurance policy to pay for cryonic suspension (the only real life insurance, I think; what most people buy is death insurance), plus $150/year in Foundation dues. A small price, I say, for a chance to see the third millennium.
