no matter how often you bathe, the number of microorganisms on your skin remains roughly the same. in fact, showering daily is not recommended by most doctors, as it strips off the outer protective layer of skin and moves bacteria around to areas where they may cause infections.

you have the same number of bacteria on your body before and after a shower. all the shower does is move them around and strip off the layer of dead skin that helps to protect you from disease.

93% of americans would never reuse someone else's bath water, but 40% don't take a shower before using a community pool.

side note: you know that strong chemical smell that some pools have? you might think it's chlorine, but it's actually the smell of the chlorine reacting with pool contaminants (ie, pee and poop). a clean pool has almost no smell.
