@ zapped, my bathroom is humongous, and the toilet is in its own room, with a closing door. What you described is a big reason why I like that. In some parts of Europe, it is considered weird to have the toilet in the same room as the sink, shower, etc, if it can at all be avoided. I'm not a Euro-phile about many things, but I think they got that one correct. Ew.
OTOH, some recent studies indicate that the sharp increase in some illnesses and diseases may be due to our environments being too sanitized. Kids grow up these days with too little dirt and germs around, don't build enough antibodies. Farm mothers actually even have more antibodies in their breast milk than city moms do. Seriously - it's true.
