aren't there reports out there from persons who had severe hypothermia and survived and said that there was no pain
I seem to have read something like that
pain is a weird thing too
many humans will go to great lengths to avoid even tiny amounts of it
on the other hand
I met a guy who had his leg ripped off in a motorcycle accident and felt no pain
he didn't even realize what had happened to him until he tried to get up
I did learn in school that sympathetic nervous system responses (fight or flight) include anesthetic endorphins, I just didn't realize how effective those are
just a few odd thoughts on the matter
