I would call myself a hygene nut, but I'd say I'm about average in making sure I'm clean.
I usually brush my teeth once or twice a day, I'll shower every day that I have work or am going out (~5 times a week), and I'll wash my hands after going to the bathroom, when I get home, or during any breaks at work. I also use hand sanitizer at work, but that's just because you never know what you might be coming in contact with throughout a long day.
