Our spine is made up of bones and cartilage, they are stacked one on top of each other. Though bones are hard and strong the cartilage is soft and compressible. Because of this if we don’t keep our spines in the proper position the cartilage gets damaged and we develop neck pain, back pain and even shooting nerve type pain going down our arms and legs.
So we must maintain a straight spine posture, keeping our ears, shoulders over our hips at all time either while sitting or standing.
