So it does make me wonder about the chances of running into a person on the street who is currently wearing (is that the right word, wearing?) a diaphragm compared to the chances of running into a person missing a kidney. Especially considering that a person missing a kidney will be missing it 24/7, but a person with a diaphragm currently inserted at any given moment, of the very few who use one at all, and out in public for god's sake, would be, I'd guess, pretty rare.
This one will be ready for the laughing dogs soon, very soon.
