I'm 24 and so at times, I put on a sweater and go outside and see that people always stare at me and say if I'm not dying of the heat or things like that, but I can't feel it and when I do my body doesn't sweat if not it gives some sort of jolts of freshness and it makes me more active then before. And for the cold it more rare but sometimes I'll just go out in a white T-Shirt and shorts but I can't feel it either and sort of like before my own body generates heat on the inside warming me but my friends say that my skin is really cold on the outside
Should I so something about it, or is it normal, some sort of adaption?
