I know I m hardly normal, but why do people spit?
I smoke and don't feel the need to spit. Surely if you get rid of saliva your body just produces more to replace it?
I think it's just a way for weak people to make a very antisocial mark on the world, like public farters.
Happily though, people that let rip a fart in public aren't putting your life at risk of disease.
