How does aging typically affect the spine?

Aging typically leads to changes in the spine that increase the risk of degenerative conditions and reduce overall mobility. As individuals age, the intervertebral discs in the spine can lose hydration and elasticity, leading to conditions like degenerative disc disease. Additionally, the natural wear and tear on the spine's structures, such as the vertebrae and cartilage, can result in osteoarthritis. These issues contribute to a decline in mobility, making it more challenging to perform everyday activities.

Furthermore, the bones may become more brittle with age, which can lead to an increased risk of fractures and further compromise spinal health. Muscle strength also tends to decrease, which affects spinal support and stability. Thus, option A accurately captures the relationship between aging and spinal health, highlighting the potential for degeneration and reduced mobility as individuals grow older.
