I worry about cracking my bones at times (knuckles on fingers and toes). I wonder whats actually cracking; the bone, cartilage, or something else? o_O; It disturbs me a bit to think about.
As I understand it, the noise comes from air bubbles escaping inside the joint.
but I also worry about whether or not it's harmful.. especially with the amount of times I crack my fingers/elbows/knees/wrists/ankles/etc every day.. sweatdrop. I don't think there are any studies on the subject that give a definitive answer on whether it's harmful or not. The good news is I'll be a good case study, so you'll know well ahead of time whether or not it has negative effects :XP:
