One man cracked his knuckles in one hand for 60 years and not the other. Watch the video to see what he found out.

OK, so I’m not a knuckle cracker but I know others who are. I suppose it’s one of those nervous habits, like biting your nails (which is more my style).

So is the old wives tale true? Does cracking your knuckles cause arthritis? I suppose it would aggravate arthritic joints, but does it create it? I’m going to say no that it doesn’t, but share your thoughts in the comments.
