I was having a discussion with a friend who also has health issues as to, "How often do most people shower or bathe?" She commented that it's too bad you can't really ASK anybody that, because they'll retort "Why? Do I stink?"

I told her that I know just the place where I can ask people that.

This relates just to actually climbing in and out of the shower/tub, and not sponge baths or wash-ups.
