The spine is a very important bone in your body. It is our body’s central support structure. The spine helps us to keep your body upright and connects parts of your body together such as your head, arms, and legs. The spine is very flexible due to the ligaments and disks it is made up of. Fun fact: your spine’s length is dependent upon how tall you are. The average length for men is 71 cm and the average length for women is 61 cm. Your spine is vital to your body so make sure you keep it healthy and strong.
