The image of a fat man in a sauna is a bit of stereotype. This never made a lot of sense to me. Surely, thin men are as likely to go to a sauna? Think I finally solved this conundrum today: fat men have a good layer of insulation around them; so, they will heat up more slowly than otherwise; which means that they will be in the sauna for longer. Which means that, at any one time, there will be an over-representation of fat men.
