What is your purpose for bathing regularly?

I was just thinking about this pick

and I was wondering why people are so grossed out about not bathing daily. (bathing=taking a bath, sponge bath, showering, anything of the sort)

What is it everyone is trying to wash off?
don't get me wrong, I dusche daily, but I'm beginning to wonder why. I think as long as we're not sweating oder rolling in dirt, we should be fine.

Is there a certain odor people are getting rid of? Where does this odor come from if it's not sweat?

I'm not letting this change my clensing habbits at all, oder any of yours. I'm just curious.
