Much to my mother’s chagrin, I have been a knuckle-cracker for life. I’m guessing if there were a way to monitor it, chances are doctor’s would have seen me cracking my knuckles in the womb. Not just knuckles, though. We’re talking toes, neck, back, ankles, knees, and when I can get them at the right angle I can even pop my wrists. I know, I know, it’s so horrible for me! My entire body is going to be wracked with arthritis by the time I’m 40, right? Well, turns out that might not be the case. And thank Goodness! Turns out when a joint is cracked what’s really happening is the gasses that were built up in the fluid of that joint are forced out of it and we hear a cracking sound. But don’t take my word for it, check it out!
I think what happens is sometimes the gasses build up in such a way that it makes the joints feel stiff. So while cracking them doesn’t hurt them, it does provide a temporary relief of that stiffness. And a really cool sound.
