What is a common physical change in later adulthood?

In later adulthood, a common physical change is the weakening of bones, also known as osteoporosis, which involves a loss of bone density and structural strength. This condition tends to develop due to a combination of factors, including hormonal changes, decreased physical activity, and nutritional deficiencies, particularly in calcium and vitamin D. As individuals age, the balance between bone renewal and deterioration shifts, leading to increased fragility of bones, making them more susceptible to fractures and breaks.

The other options, such as increased height and weight, improved mobility, and enhanced muscle strength, generally do not reflect typical changes experienced in later adulthood. Height usually decreases due to compression of the vertebrae and changes in posture, while muscle strength often declines due to factors like reduced physical activity and muscle mass loss (sarcopenia). Mobility may also become limited due to joint issues and overall weakness, contrasting with the idea of improvement. Therefore, weakening of bones is a significant and recognizable change in this life stage.
