Think about this current day and age in regards to posture. Your neck is in forward flexion every time you’re at a computer, on a cell phone, scrubbing, sweeping, gardening, studying. This constant stress and pressure eventually leads to permanent slouched posture and neck tension. This is a major contributor to people getting shorter as they get older. If you are already having neck or upper back pain without any known cause, it is likely that degenerative changes have begun.
