I don't understand how anyone can take more than two showers a day (one in the morning, and a second one at night or before you go out). When you take that third shower do you put on the same clothes you were wearing before you took the shower (including underwear)? Also, how do you find the time to take a shower more than two times a day? When I'm out and about I'm usually out for the entire day, I can't imagine finding the time to take three, four or five showers a day even if I wanted to. Then again, maybe our definition of what a shower actually involves is just different.
Anyway, I usually take a shower in the morning and, depending on what I was doing during the day, (sports, swimming, working out, haircuts, etc.) another before I go out again or later in the day. I usually don't take a shower right before going to bed because I don't have a specific bed time, instead I've resolved to wash my sheets more often.
