Hi everyone!

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
