Curiosity only.
Here in Brazil it's very common to have several showers a day. I, for example, take two. The first is when I wake up, before I go to work, and the second is when I get home from work. I wake up at 6.30am and get home at 8pm.
edit: I said bath, but I meant shower.
Live in Germany but originally come from the Failed States of America. I normally shower twice daily, unless I'm staying in the apartment all day and not going anywhere then I can do once. Do not have a bath tub, probably wouldn't use it much if at all if I had one
Basically my routine. If I have to stay at home all day, I'll only take one, but that's rare.
