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.
Unless I'm doing yard work or similar, I will shower every other day, sometimes 2 days. My skin gets unbearably dry and itchy if I shower more often.
