cracking your knuckles is not bad for you its an urban myth, the cracking sound you hear when you pull on your fingers is caused by the release of negative pressure within the joint, as the fluids between the joints move around. When you pull, you break the vacuum seal created by the fluid and the breaking of that seal causes the popping sound.

:lol: I was once given the same speech from a cocky little IT guy in my last job when I said it was bad for him... I stand corrected then and now...
