Your body's joints enable you to enjoy movement. A primary function of the joints is to hold the skeletal structure of your body together. Simply stated, the joints act as the glue that helps hold the skeletal system together and permits its movement. The cartilage found in a joint act as cushion between bones. Maintaining normal, healthy joints should be a life-long goal. To achieve this, it is important to adopt a healthy lifestyle. Elements of healthy living that help maintain healthy joints include: sustaining a healthy body weight, regular and appropriate exercise, and eating a nutritious and healthy diet.
