Which statement about physical aging is true?

• A. Both men and women exhibit loss of physical fitness.
• B. By the fifth decade, individuals gain 10-20 pounds.
• C. Muscle strength and flexibility increase with age.
• D. Wrinkles are caused by loss of skin elasticity.

Answer: (A)

A universal decline in physical fitness accompanies aging, affecting both men and women. As people age, they typically lose muscle mass and strength (sarcopenia), experience reduced cardiovascular capacity, and see decreases in flexibility due to changes in connective tissue and joints. These changes happen regardless of gender, so statements about both men and women sharing a loss of physical fitness are true. Weight gain by the fifth decade isn’t guaranteed for everyone; body weight and composition vary widely with lifestyle, activity, and genetics, so a fixed gain of 10–20 pounds isn’t universally applicable. Muscle strength and flexibility do not increase with age; they generally decline, making improvements in these areas less likely as years pass. Wrinkles are influenced by multiple factors, including sun exposure, collagen and elastin degradation, and overall skin hydration—not solely by a loss of skin elasticity.
