Lets face it Walabio is chatting … He is obviously a very bored person who has nothing better to do than criticize other people's ways of life.
If he wants to stop cracking then let him do it!
Walabio you don't have any knowledge about the long term effects of joint cracking at all. All he is going on is his own pre-conceptions.

I can pop my jaw by placing the palm-h**l of my hand on the muscle and then pushing in.

Have a cracking good time!
