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.
I'm also an evening showerer. I don't know how people navigate the world all day, participate in traffic, be in dusty wind, cook, etc and then get in their bed and sleep comfortably.
