Are you a Stander or a Sitter?

I don’t even know what to say about this article… I’m not about to start peeking over bathroom stall doors to satisfy your curiosity!
A recent article in Mainichi reports that 40% of Japanese men sit down to pee.
Has this kind of survey ever been done in the US? Isn’t it an insult to imply a guy sits to pee?

40%? When not already having the need to be (get where I’m going with this indirectness?) sitting on the toilet for another more number twoish reason?
