Vertebrae also lose some of their mineral content, making each bone thinner. The spinal column becomes curved and compressed (packed together). Bone spurs caused by aging and overall use of the spine may also form on the vertebrae. The foot arches become less pronounced, contributing to a slight loss of height.
