As a bald man, I've noticed that the less hirsute I get cranially, the more I get elsewhere. My eyebrows can now be combed over my head, replacing the hair lost there, to say nothing of the ear hair, which can replace sideburns nicely. As for the belly button, I wouldn't know if there's any lint there, since I can no longer see it through the black forest of fur. And, worst of all, there's a thicket in my - uh - umm - nether regions. This appears to be primarily a male phenomenon, thank goodness! So now you know why I wear a hat - to hide my fuzzy face! And, yes, it's damned cold in the winter and hot in the summer without one.
