I'll agree with almost everything you said. I fail to be convinced that cracking or popping a joint is a valid treatment. Joints that crack or pop is a symptom of a problem in that joint. I know I've failed to convince you either. We'll agree to disagree & stay friends.
I haven't had any medical training other than being EMT certified for a while but my family runs deep in medical (2 doctors (both medical imaging), 2 nurse practitioners, 1 Occupational Therapist & 3 more in medical training now). I'm just used to hearing the negatives I guess.
