I'm having an umbilical hernia repaired soon. They're going to shave major parts of my anatomy in preparation. (I'm not sure how much, but I'm guessing at least my abs and pubic hair.) I'm moderately hairy everywhere but my back. The question: should I trim the body hair, or just let 'em shave it the way it is? Or should I shave myself, and let them tell me if it's good enough? I figure whatever they or I do, I'm going to shave completely afterward, so it can all grow back at the same rate, and not look so freakish.
