You name it.  Place any word or noun in the blank to finish off that statement and it makes sense.  In life, movement dictates quality.  The perfect balance of intellectual, spiritual, and musculoskeletal movement creates the ideal life for any individual.  If this movement ceases in any way, we die.  Reversely, too much movement can create problems as well.  Our ancestors used joint mechanics in the designed way out of necessity, in order to survive.  In modern society, leisure/technological advancements have created sedentary lifestyles for individuals because of the lack of necessary movement.  This has created a myriad of issues for our species, and it is being passed through generations without being resolved.  Only with the reparation of  these movement dysfunctions in the body and mind can the human race stop chronic disease created by a poor lifestyle.
