Eliezer, I have been a frequent and enthusiastic participant on /r/hpmor for years before I decided to buck up and make a LessWrong account.

The most common sentiment about cryonics is "God dammit I have to stop procrastinating",

I don't recall someone answering my question in the other place I posted it, so I might as well ask you (since you would know): provided I am unwilling to believe current cryonic techniques actually work (even given a Friendly superintelligence that wants to bring people back), where can I be putting money towards other means of preserving people or life-extension in general?

Gwern had a posting once on something called "brain plastination", which supposedly works "better" in some sense than freezing in liquid nitrogen, even though that still relies on em'ing you to bring you back, which frankly I find frightening as all hell. Is there active research into that? Into improved cryonics techniques?

Or should I just donate to anti-aging research on grounds that keeping people alive and healthy for longer before they die is a safer bet than, you know, finding ways to preserve the dead such that they can be brought back to life later?
