Hehe. I don't actually ever touch ANYTHING in a public restroom...when one flushes a toilet, unless the lid is down, the matter that swirls around the bowl gets aerosolized, and countless particles actually fall all over the room for up to 6 hours after the flush, according to the latest scientific research (yes, people actually study THIS :Q ). Of course, most public toilets don't have a lid, so every surface in the room is chronically contaminated.
