Which of the following is not a controllable risk factor?

Age is classified as a non-controllable risk factor because it progresses over time and cannot be influenced or changed through behavior or lifestyle modifications. As individuals age, certain health risks tend to increase regardless of their habits or choices. In contrast, smoking, inactivity, and cholesterol levels are controllable risk factors. Individuals have the ability to eliminate smoking, increase physical activity, and manage cholesterol levels through diet, exercise, and, if necessary, medication. Understanding the difference between controllable and non-controllable risk factors is crucial for effective health management and improving overall well-being.
