Just to take our minds off more serious concerns for once, I thought I might point out something I have noticed that other people might or might not be able to confirm from their own experience. I have noticed that people whom Australians would call "drongoes" (foolish and stupid people) are very prone to wearing woollen hats -- beanies etc. Australians very rarely wear hats of any sort even when they should (given our high incidence of skin cancer) so people wearing warm head-coverings do tend to stand out. And from listening to such people and observing them for many years I am much struck by the low-grade intelligence that seems to prevail among such wearers. No doubt that would not apply in really cold countries such as Russia where furry hats significantly enhance survival but Australia is a generally warm country where few people feel the need for top-deck insulation. So when I see a beanie-clad head in the streets, I immediately identify the person concerned as one best kept away from: as someone with a probably significant tendency to crime and violence. Having been for some years a boarding-house proprietor in a down-market suburb, I am well aware of the fact that crime and violence is a common way for drongoes to cope with life.

So why the association between social pathology and a desire to keep the head warm? I think it is no mystery at all. The brain uses up about 20% of the body's energy. It is a huge consumer of calories in relation to its mass. So the head is normally the last part of the body that feels cold. Having the brain inside the head working is like having a radiator inside it. And as far as I am aware, active brains use up more calories than less active ones. So the people with the relatively inert brains put out less heat from the head and thus feel the cold in their heads more than others do. So an unusual need for warm head-coverings suggests an unusually inactive brain. That's my theory anyway.
