I'm a little late to the party, but I must voice one of my strong beliefs:

Women should not pee standing up.

There was one occasion last week in France where I had to use a bidet, and, well, I don't even know exactly how you're supposed to "aim," but let's just say that I wasn't very successful.

And to further coroborate my point, I have never seen a bidet in a French residence. Only this one time at a mall in Strasbourg.

But apparently, some people believe it's a good idea for women to pee standing up, and I guess I must salute those who can actually do it successfully.
