Just as your car needs shock absorbers to operate properly, your body also has its own set of shock absorbers. The discs (or "shock absorbers) of your body and spine work with the natural curves of your spine to reduce stress and pressure as you move. These discs separate each vertebra, and create the space needed for your nerves to exit your spinal cord, which is what allows them to keep your organs and body tissue healthy. Rings of fibrous tissue called the annulus contain a soft jelly center. You need these to be healthy and aligned, keeping your body on track.
