I've mentioned it a handful of times, so I'm sure Zelda already knows, but I'm an orderly in my hospital's ER. I've seen, not to mention smelled, things...
What makes you say that, Leah? I handle the bodies of patients who have passed from time to time. Also, you'd be surprised at the number of people who don't come to the hospital until AFTER a good chunk of a limb has gone gangrenous.
It's called your tongue.
