Cracking Knuckles

Cracking one's knuckles in good health doesn't cause arthritis or other issues. The cracking sound comes from a gas bubble forming when the joints separate.

Now quit telling me to stop cracking my knuckles!!

I get that it grosses some people out. I had a buddy in high school who could tilt his head to the sides and cause his vertebrae to crack. It was a bit unsettling.
