Yeah, I say that, but the story I have in mind is set in a frozen wasteland, and I'm definitely going to use my personal experience trekking through the Canadian wilderness in the middle of winter to portray realistic reactions to the cold. (AKA: if it's windy and -35C, you can't really tug a glove off to do something delicate with your hands.) I've read stories - and watched movies - in which it's clear the creators had never experienced cold like that for themselves and... yeah, it was jarring. Research = good. ;)
