Among the other parts of your body that you use every day, your back supports your frame and body when you are sitting all day in front of your computer. Your back acts as foundation when carrying items, both light and heavy. Even if you carry items on a daily basis, you should not be unaware of the pressure that you are exerting on the tiny bones of your back.
Your spine is made up of many bones called vertebrae, and between each vertebra is a disc. The discs are made of strong rubber-like tissue that allows the spine to be fairly flexible. Strong ligaments are attached to the vertebrae and these give extra support and strength to the spine. All these parts of your back enables you to do various activities everyday.
