Most common people wipe after a bowel movement, what if we were like canines and DID NOT have to wipe? I suspect there would be fecal matter everywhere, sidewalks, elevators, conference rooms, treadmills, saunas, etc. etc.
I recall on a summer job while in university this one person would defecate everywhere and no one could catch him. One electrician put his hard helmet down to wash up and when he came back, the person took a huge dump in it. He also wrote on the office wall, "The Mad Shitter Strikes Again" all in his own waste.
