The thing to remember is that damage from freezing is not the critical question: the question is whether or not such damage is repairable. Cell structure is the main thing, and structure may be preserved even if full function (for the moment) is not. If, for instance, temperatures fall way below zero in the winter, your car may very well may not start, and if it's left that way long enough, damage may occur and it may not start even when things warm up. But that doesn't mean your car is utterly and completely demolished and unrepairable, as though it had been buried and rusted into particles over the course of centuries. Studies indicate that freezing damage is rather like that: it disarranges brain cells somewhat so that brain activity stops. But it doesn't pulverize a brain cell into dust, so totally that its original, functioning, form is completely obliterated and unrecoverable. On the contrary! It preserves the original structure, which is precisely why the cell - and the brain -- is repairable. Not quite at the moment, granted; but methods currently being developed are bringing that moment closer and closer..

I would personally have killed a million monkeys, if it would have advanced science enough to have saved my 5 year old sister from dying of lukemia.
