The most mistranslated haiku of them all of course, because it's not really about personal hygiene, but he's got a point, even if that isn't what he meant. A house you only have to paint every five to seven years (according to a tv show I saw). But the human body needs an incredible degree of maintenance to keep it externally pleasing. Every morning you've got to wash it, shave it, deoderise it, brush it, dress it. If you don't it deteriorates so quickly, you become a public nuisance, and your fellow human beings will reject you. How stupid, as the haiku writer says, given our fancy notions about our dominion over all creation.
