I just read a couple of articles about popping your knuckles. Do you know why they pop? Its because there is air trapped in the liquid around your joints, and when you stress them, the air gets released from the liquid with a popping sound. The reason you can’y pop them again for a while is because it takes like 30 minutes for the air to go back into the liquid. They also say that there is no clinical link between popping your knuckles and arthritis.

Even so, I want to stop popping my knuckles. They hurt after I’ve done it all day, and its a nasty habit anyway.
