Is cracking your knuckles bad for you?

Some believe that cracking your knuckles can actually cause arthritis. There is no scientific evidence at this time that arthritis is caused by cracking your knuckles. In fact, the "cracking" sound is not actually a crack so much as a release of gas from the fluid in your finger joints. It is this cracking that is believed by some to be evidence that cracking causes Arthritis, but this would appear to be an urban legend.
