Could cracking/pulling your knuckles every minute cause problems?

Crack, Pop, Crunch..: Yeah. For everyone around you. It's annoying- and makes you look nervous or uncomfortable. It's like cracking your gum all the time. And yes, it can put chronic strain on the joint capsules and lead to laxity and maybe even some arthritis down the line. Every now and then, OK (like once or twice an hour; or just before a fight). Otherwise knock it off. Try tightly clenching your fists instead.
