I love these techniques and can't wait to try them out. Would you consider putting in an abstract with the 4 techniques? You could even throw in the one-sentence summaries from ScottL so that other readers can quickly get the gist before delving in further.

Cryonics is being deeply confused with suspended animation in this thread. Cryonics has nothing to do with cellular viability. It's only about preserving the wiring and physical structure of the brain by any means necessary. In current cryonics, all cells are totally and completely dead long before the procedure is finished. But we also have electron micrographs showing very good structural preservation of these dead cells. The cryonics revival technology will need to manipulate trillions of atoms inside of each of billions of cells. No low tech is going to be able to revive them.

Clarity, you can find more bioparts at the ICE public registry:

CronoDAS, I'm glad you brought up this issue. Sadly, I don't think there's good evidence that cryo, as practiced today, works. I think it is reasonable (but of course, not ideal) for people to dismiss things which are only theoretically possible but not practically possible.

If we had verifiably working cryo today, it might be easier to change people's minds.

Hey Alexvermeer, could you give more details on the opportunities for advancement?

Hey lululu, this was a great article! I found it very useful in dealing with rejection by a long-standing crush. Thanks for writing this.

I'm curious: what was your process for determining the best way to get over a relationship? Did you just search for that term in Google Scholar?

I get the sense that many of the people who have signed up have done it less for the increased survival chances or the sense of comfort, but as a sort of flag waving. It is pretty good signalling that you are opposed to death and part of the ingroup that is opposed to death. Those little medallions are badges of a refusal to submit to the awful thing.

Cryonics will definitely fail if the peace-of-mind cryonicists dominate it instead of the serious adults who want to survive. 

You can see most cryonicists' fundamental lack of seriousness from the fact that they talk a good game about how much they believe in scientific, technological and medical progress. So what happens when you try to draw their attention to the many correctible shortcomings in the real, existing practice of cryonics? They usually shrug those off as if these problems don't matter.

Uh, hello?

This fundamental lack of an evidence- and reality-orientation in many cryonicists goes a long way towards explaining why mainstream people don't find the cryonics idea credible, much less its haphazard implementation. I just have no patience these days with cryonicists who invoke Eric Drexler's discredited fantasies from the 1980's, or who make fallacious comparisons between cryonicists and the Wright brothers. Cryonics falls into the overlap between neuroscience and cryobiology, and progress in it will have to come from the application of those real sciences.

I don't understand the distinction being made. The chance of revival and peace of mind aren't separate things: it is the former that causes the latter.

If you are not a cryonics member, what would make you decide that it is a good idea?

I don't think it's a crazy idea, but I'm not signed up. I might reconsider after some leaps and bounds in the technology, like successful short-term freezing and revival of humans. I am not expecting to see that within my expected lifespan.
