My pal Michele of Crowded Teeth told me a cute story about a friend of hers who got her boyfriend's kidney after one of hers failed. It seems he's a very big guy and she's very wee, so her newer and larger kidney sticks out a little bit. I never really thought about the fact that -- duh -- your organs are proportionate to your body size. Obvious, but interesting. Hell, if that kidney fits, go ahaed and wear it.
