Which is a common physical change associated with aging?

Decreased muscle mass and loss of bone density are well-documented physical changes that often occur with aging. As individuals grow older, it is typical to experience a gradual decline in muscle mass, a condition known as sarcopenia. This decline results from a variety of factors including hormonal changes, decreased physical activity, and changes in nutrition. Similarly, bone density tends to decrease due to a reduction in bone-forming cells, leading to conditions such as osteoporosis, making bones more fragile and susceptible to fractures.

Understanding these changes is important for promoting healthy aging. It can inform interventions such as resistance training and adequate nutrition that have been shown to mitigate some of these age-related changes. Recognizing that these physical changes can impact mobility, strength, and overall health underscores the necessity of preventive measures and proactive health management as people age.
