I'm thermally impaired. I can barely feel any heat or coldness at all. Unless I have some long sleeve shirts to wear I'm normally seen around town in my heaviest coat, which I wear for two main reasons:
1) I carry all kinds of stuff around with me. One pocket I only use to hold my money box and a coin that I made with an Elven rune for "chaos" imprinted on it; in another pocket I have a pair of gloves, a tape measure, a level, a pad of post-it notes, a pen, and a two-year calender/planner with a kitten on the cover; in the inside pocked I carry one of my flash drives, my chop sticks, a mechanical pencil, and my sunglasses; in yet another pocket I have three small boxes of matches, the metal box that my watch came in that I keep all of my mechanical pencil refills and occasionally my MP3 player in, and sometimes a deck of cards if I feel like I'm going to need them... To carry everything around that I normally have in my pockets I would need a gym bag or something.
2) To keep my skin nice and pale. I've barely exposed any of my skin to pure and direct sunlight in the past few years aside from my face and hands. Most people think that White & Nerdy should be my theme song just because of the "Whiter than sour cream" part of it =D
