You are completely misinformed. Even under the worst current procedures 
all ice crystals form extra-cellularly. Cells are shrunken but not 
ruptured. Under the best current procedures no ice crystals are formed 
at all. The only damage is due to cyroprotectant toxicity. It is 
currently not clear whether such damage is ultimately "fatal". Only time 
and future medical advances will tell us that. In the meantime, work 
continues to develop fully non-toxic cryoprotectants which still allow 
no ice crystal formation. With funding of only $10 million per year it 
is almost certain, IMO, that this could be accomplished within 5-10 
years and that within 15-20 years fully reversible long-term human 
suspended animation would be available for all who live in 
technologically advanced countries and wish to have it. This would 
accomplish an end to individual death from most non-accidental causes 
since once in suspended animation one could wait as long as necessary 
for the necessary medical advances to fix what put one there and also 
for the life extension advances needed to rejuvenate one. In that sense 
fully reversible long term human suspended animation would be like an 
ambulance ride to the future.
