Ooh, nice to see such a title while eating. Puts some extra psychological spunk into my dumplings. Yum.
From what I hear, smoking can make the body produce greater amounts of saliva.
I've personally never been a spitting type. Only when I really need to. I have done it a few times to cut off my brother's talking (he dislikes it even more than I do; honestly, if you knew what he sometimes talks about, you would sympathize with me
). Other than that, I just about never do it.
I remember walking home from school one day with my friends. We were in the 7th grade or so. One of them asked me, since he'd never seen me do it: "Damn, Peeter, why don't you ever spit? Go ahead, just do it once," then added challengingly, "or maybe you just can't do it?" My answer was something along the lines of "nope, no sirre, can't do it. Nuh-uh, that's not for me." Okay, so I wasn't a very cool guy but the bottom line is I regarded smoking as too disgusting to just demonstrate it.
