I can never get my fill of diseased-heart visuals. Just in case I didn't find the examination room comfy enough, I'm provided with these vivid images of cut-open organs. On the other wall is a giant blow-up of a gangrenous toe. What am I supposed to do with this information? Am I now supposed to be able to identify gangrenous toes out in public, so that I may direct the owners of same to appropriate medical care? I'll tell you one thing: if I'm ever thrown into a situation where I'm confronted with a butchered human heart, identifying its disease will have to take a back seat to screaming in terror and voiding my bowels.
