Newton's law: A body in motion tends to stay in motion, and a body at rest tends to stay at rest, unless acted upon by an outside force. Chiropractic is that force! We add motion to the spine and nerve system, thereby helping that body that was at rest (with whatever ailment) become a body in motion (healthier). The key thing is that once the body is in motion (healthier), it tends to stay in motion! But you've got to keep up the things that got it in motion in the first place!
