In my model of health and wellness, chiropractic is not a spoke in the wellness wheel, on par with diet, exercise, positive mental attitude, good sleep, etc., but rather, chiropractic is a foundation that all these lifestyle things are built on.
You see if you have limiting patterns in your nervous system, then exercising and supplementation, etc. will have an incremental effect on your level of wellness relative to this limited neural capacity. It helps, but can only take you so far.
When a person is adjusted and has improved neural function, a whole world of creation and possibilities opens up that allows these lifestyle changes to take a person to wellness places they have never gone. It literally takes them to new frontiers!
