Do you crack your knuckles?

I try not to do it when other people are around... but I definitely do it. Every joint of every finger... the wrists and ankles are fun, too. Used to pop my neck, too, but that became too absorbing and too headachy if it didn't pop... so I weaned myself of that habit.

The first wife and I used to sit on each other's back and pop the vertebrates of the upper back... very stress-relieving, but that scares my new wife so we don't do it.

Health professionals seem to think the practice is harmless in the long term... Interesting that I'm going on 62 and don't have the arthritis problems a couple of my sisters are beginning to have (knock on wood). Maybe just coincidence... crack.
