What kind of cow?
This is pretty silly actually, but what the heck. During my years having a bovine valve, I kind of always wondered "what kind of cow" did my valve come from? A regular hamburger cow? A special medical cow? (somehow more sanitary if there is such a thing). Maybe a mad cow? Do they use only a certain type of cow or are all cows welcome?
Same goes for porcine valves. Your thoughts?
