Well, that #17 was a no-brainer, cause I constantly (most) get that reaction from others who think it is a "bad habit" (I regularly adjust not just my hands, but my back, neck etc).
I had a Chiropractor (years ago) tell me the truth about the knuckle thing. But for some reason, some folks just refuse to let go of a "lie". Does not make sense to me.
