Some comments on personal hygiene in another thread (For Godsake let them shower . ) brought this to mind. When a guy at a gym near you showers in his underwear you might consider him strange. But when he takes only the briefest of required showers (in his swim suit t that) before going into a public swimming pool (hot tub or whatever) you can consider him a public health risk. In the past thirty years Ive had just about every kind of eye surgery possible. And I no longer go NEAR a public pool to avoid the risk of infection. Too many people put on their swim suits, hop into the shower long enough to look a little wet and make no attempt at all to clean their most pungent places. All the perfumes of Arabia, etc., etc.
