I am a walking mass of chemicals that was forcefully expelled from the womb a number of years ago. I will eventually grow old and fat before expiring completely, at which said state my carcass will be shoved into a box and buried beneath the earth.
Actually, I've only used it a couple of times and I usually take the offender off of it after I've cooled down. I really haven't felt the need to keep anyone on it, so the number is zero.
