I told Kenneth Storey, who studies various animals that can be frozen and thawed, about a new $60M government initiative (mentioned in Wired) to find ways of storing cells that don't destroy their RNA. He mentioned that he's now studying the Gray Mouse Lemur, which can go into a low-metabolism state at room temperature.

If the goal is to keep you alive for about 10 years while someone develops a cure for what you have, then this room-temperature low-metabolism hibernation may be easier than cryonics.

(Natural cryonics, BTW, is very different from liquid-nitrogen cryonics. There are animals that can be frozen and thawed; but most die if frozen to below -4C. IMHO natural cryonics will be much easier than liquid-nitrogen cryonics.)
