Topic Reading-Vol.165-9/23/2012

Dear MEL School's Topic Readers,
Does cracking your knuckles cause arthritis?
Some of you may like to crack your knuckles by pulling the tip of each finger one at a time until you hear a crack or others may make a tight fist or bend their fingers backwards away from the hand, cracking the lot at once, may be for the purpose of relaxing your knuckles.
Either way, you might have heard that knuckles cracking may damage your cartilage. But is that true and how much?
Enjoy reading and learning this interesting study result.
