Male, 19 years old. Shower every day (at worst every other day, but not often), not like I do anything, but when I do decide to take a jog or go walking with the dog or do some yard work, I'll just shower twice that day.
When I used to play MMOs (early high school), I'd sometimes forget to shower over the weekend and then wake up Monday morning in a rush to shower! (Only because I had nowhere to be though and honestly didn't care)
