I knew someone a few year ago who had a sex-change (male -> female) operation.
After he became she I wondered how her how her body was feeling. Surprisingly, she said the biggest problem was that one of her nostrils was enlarged, and was a bit sore.
That made absolutely no sense to me - I'd expected she'd talk about the changes she'd experienced below the head. However, when she told me that the doctors had needed to put a straw up her nose in order to suck out half of her brain it all made sense.
(Just kidding, ladies, honest!)
