Do you crack (or pop, whatever) your joints? I've always done it for as long as I can remember.
It doesn't hurt or anything, and sometimes actually feels quite nice. I love it when your back or shoulder or something pops and it feels great.
I usually get quite a few pops out of all my fingers when I go off on a popping spree, more than a couple per finger. I can pop one of my toes over and over again also, for as long as until my toe gets tired.
How about you ?_? I don't mind people doing it, but some people seem to feel quite uneasy when others do it, such as my mother.
