X-Message-Number: 12122 From: Thomas Donaldson <> Subject: Re: CryoNet #12116 - #12119 Date: Wed, 14 Jul 1999 00:12:42 +1000 (EST) To Magnus Redin: Yes, experimenting with nonhuman subjects will be very important. I doubt that any cryonicist wants to be revived without previous such experiments good enough to develop methods to revive him/her to as good a state as possible... not just experiments which succeed in reviving an animal, but experiments which not only revive the animal but leave it in good health afterwards, with as much memory as possible. However freezing at the temperature of liquid nitrogen creates a situation in which no significant changes will occur for thousands of years. Even warmer (but well below 0 C) temperatures should keep someone virtually the same for hundreds of years. (Once freezing turns you into a solid, you're about as durable as rocks --- though you could be easily shattered, just like some rocks). Basically this means that we need not freeze and store any animals now for future experiments. What we do need to do, and it is done by all the cryonics societies, is to record as carefully as we know how just how a patient was frozen. This allows future scientists/doctors to carry out the same procedure on animals and thus study how to revive patients frozen by the same methods.
