I don't feel cold (I feel warm) at all (except for my hands) all my life, what is it?

In the winter when there’s -10C (when there’s less I’m starting to feeling warmer and warmer as it gets more cold -> that means it’s bad). I’m wearing t-shirt without sleeves. I don’t feel cold at all for as long as I remember. (I almost froze to death as a child, but it was due to the fact I was in the mountains at winter in t-shirt. I wasn’t feeling cold even then. I just felt sleepy. So I laid down, and teachers has to carry me.) Only in hands (the palms and the finger joints), but those are almost as ice instantly (other people description) when exposed to cold. I’ve to wear two pairs of gloves, and I still feel slight cold. Like all the “cold detectors” are in my hand instead of distributed evenly in my body. I’m not sure about warm thou, I’d swear that I feel warm. But maybe it’s just recognized by change in the tension of skin, or something else (sweating), I’m not sure anymore (as I when younger). Cold “feels” different than warm (without feeling it – I mean by feeling only pressures). I really prefer cold against even slight warm (sweating, I can’t think clear).What is it ? Is it known ? Is it some genetic defect. I’d really like to know the answer.
