I have always had the habit of cracking my knuckles.  I know it has irritated people I've been hanging out with, but I just can't help it.  I've also heard that it's bad for me and could lead to things like arthritis, so when I saw the title of this video I had to find out.

I did hesitate watching this at first, because I'm not sure I could break habit either way.  But, I bravely started the video and now I know the answer.  It's time for you to find out as well.
