A big part of being a human is that you get progressively more gross as the day goes on. Various parts start stinking, hair grows all over your face, you're touching who-knows-what... luckily for all of us, someone a long time ago decided to invent hygiene! Otherwise we'd have to lick ourselves like cats!
