When I was young, I was told if I crossed my eyes that they'd eventually stick like that and the docs would have to perform surgery on me to free them! Man, gotta say I was duped by this next old wive's tale tooMaybe they told us we'd get arthritis because cracking your knuckles is just plain annoying to most people. Well, crack away because it can't hurt. Literally!

Apparently all you're doing is creating an air bubble and then popping it when you crack your knuckles, and it FEELS good! However it won't feel all that good if a big huge burly dude in a dark alley or biker bar does this and starts walking towards you. If so, old wives everywhere (and yours too) encourage you to RUN!!
