Every freaking joint in my body cracks, and I have a (pseudo-) neurotic need to do so on a daily basis. With the knuckles, it's just habit; with the neck and back, I genuinely feel very stiff unless I do so. Am I damaging my body in some way? Most of the advice I've heard on this issue has been from people with an agenda (i.e., they are annoyed by it) so I don't trust them.

Previously noted here, but didn't see the answer to my specific question.
