Mostly I bite my fingernails... trying to stop though.
I have a sort of weird habit of randomly starting tapping rhythms, either with objects, my hands, or my feet, or all of those things at the same time... lol too much music in me
i Chew the skin of the end of my fingers... it's a horrible habit and it could lead to some nasty disease... *shudders* i Also like the smell of 'new' things, like a vacuumpacked set of playing cards...
