*sigh*
Few notes:
1. the article was meant to be a promotion of chiropractic. That should have been obvious enough by the title. It was written toward an audience that should have already been asking about chiropractic, otherwise they wouldn't have clicked on the link "parkour and chiropractic".
2. Because your father is educated doesn't make you educated

. But, you probably are on your way to be educated, I won't deny that. I'm just pointing out the fallacy of logic. Besides that, your point that popping and cracking keep your bones in place if your bones tend to move... I'm not sure I understand what you are trying to say? It doesn't really make any sense. popping and cracking your bones DON'T keep your bones in place... I'm so confused at how you came to that conclusion. Anyway, it sounds like maybe your father answered a question for you, and somehow between the transfer of information, something was lost. Because it sounds like it almost is a point....
3. Thanks derik for defending me, but I don't think it was necessary. I didn't see any attack coming in. I should point out that joint alignment, or chiropractic care doesn't necessarily have anything to do with a pop. In fact, before I went to chiropractic school, I never got a single pop out from my chiropractor. Adjustments sometimes "crack", but they are NOT the same thing.
... ok

, anyway, lets focus on the topic of this post
