My showers are typically 10 minutes or less. Had a buddy in college who would take about 1 minute to shower. Not sure how he was able to get clean, but he didn't stink so it was working.
How often do you shower? How long of showers do you take? If you shower at night, do you still shower in the morning?
My wife will take a shower at night if she works out, usually pretty quick, but still takes a shower (LOOOONG shower) in the morning to "wake up." I rarely take more than one in a day, unless I've done yard work or worked out or something and need to take another before bed. But, I won't then take another one in the morning. On my work from home days when I'm not leaving the house I'll typically skip a shower for that day (gross, I know).
