A shower takes at least 5 minutes fro boys and for girls it takes 30 minutes or less uh oh i might be a girl cause im usually in the shower for 15-20 minutes.
the average shower should only be 10-15 minutes. If you don't believe me i did soooo much research for my science project at school. So if you still dont look it up your self.
you should take a shower atleast 15 min or more>>>>it not necesary for boys who dont have hair to use shampoo but they could doe (girs do to take of flies)...
