"There is also a psychological phenomenon at work here that I believe is particularly male. A woman or girl--presuming one could be induced to take part in this sort of activity in the first place--having burned her hair and eyebrows would conclude that she had been lucky and reduce the amount of gas she put into the balloon next time. The man doesn't come to the same conclusion at all. He, singed and blackened, arrives at the point of view that he still has a margin of error to play with. After all, he isn't dead, and he's hardly likely to burn his eyebrows off again. They've already gone, history; he's moved on. There can be but one deduction--the dose needs to be increased."
