Your car needs regular maintenance, so you probably have a mechanic. Your eyes and teeth are important, so you see your optometrist and dentist regularly. You get an annual physical from your family physician. You might even be getting ready to see your accountant to get your yearly income tax done. What about your physical therapist? Do you and your family have one? If not, you should. Your body is a lot like your car. It's got multiple systems, all of which are complex, and all of which have to be working well for it to function. Physical therapists are experts in maintaining, diagnosing, and treating the movement system. Like the braking or ignition system in a car, most people only think of the movement system when it's not working the way it should.
