How about for people who aren't overweight? I hate being warm and I only begin to feel uncomfortably cold when my hands have already gone red and blue. I don't sweat any more than other people do when they're too warm, it's just that I feel too warm earlier.
I don't know if it's something medical, really - I mean, I know so many people who are the opposite, and people with no preference to warm or cold. But it is annoying.
