I have a mole where my mustache grows. I have been shaving over that a very long time. I have cut it, bled like a pig, put toilet paper on it, it saturated the paper, I do it again and again until it finally stops getting so bloody that it falls off, I go to work, it looks all dry and crusty red, I pull it off and it bleds and bleds again and then four days later I can take off the paper. Not really four days, but it seems like it. Point is this, it never went bad other than the bleding and obvious nerdiness of wearing that thing to the office.
