Do you study your stools? Parse your poo? Dissect your defecations? (Possibly NSFW)

I once saw a gastroenterologist and his aide asked me if there was mucus in my poop, and when I said, “Eww. I don’t know. I don’t look that close”, she gave me the eye, and said something to the effect of “Oh, come on, we all look!”

So, tell us, how closely do you examine the remains of yesterday’s food?
