A few comments on the damage done by freezing etc: These basically showed up on Cryonet, but years ago. They should be remembered. Basically, even without true cryonics, lowering an animals' temperature increases their survival time. Not only that, but various drugs, WITH OR WITHOUT LOWERING TEMPERATURE, also work to lengthen the time in which treated animals survive. Not only that, but some of the treatments tried could keep a patient alive for as long as an HOUR in good conditions. Other work done with parts of brains suggests that we might even someday see means to revive someone after 6 hours of normal or slightly below normal temperature (the paper here, in CELL 115(2003) 863-877, with M Tymianski as its main author. I list it here because we should know of it). Fundamentally there is a good deal we can do even now to bring down the damage caused by ischemia or hypoxia. Not only that, but there are going to be times when the best available preservation methods turn out to simply not be usable. Various methods exist right now to minimize the damage before it happens. Some of these are even now used in our suspension methods. Best wishes and long long life for all, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=27326
