comment: Bodily waste can literally be a biohazard. Plus it stinks. It's gross.
  And, if anything, this should increase the amount of respect people have for janitors. People look down on it simply because they're selfish idiots who feel the need to be "above" someone, but janitors are some of the most important and underpaid people out there. Be proud of what you do, because it enables the rest of us to feel civilized and sanitary. 
  If all janitors stopped showing up to work, those people who look down upon them would be among the first to complain.
