Why are fat people not cold? It's an absolutely freezing morning and I'm wearing one of those snug north face wind proof jackets while I wait at the bus stop. I don't mind cold mornings but it's absolutely freezing and I'm don't want to stand there and freeze.  The fat next to me at the bus stop however is wearing one of those shoulderless blouses and leggings. Those blouses are the thinnest acrylic and couldn't provide any warmth at all. She's only got the tiniest bag with her so no sweaters hidden away.  I see this happen everywhere, in the office, on the train, etc. Fats dressed completely inappropriately for the weather. Can anyone explain this strange behaviour?
