“Have you ever heard the expression “use it or lose it”? It’s true! If you don’t use your body, you will surely lose it. Your muscles will become flabby and weak. Your heart and lungs won’t function efficiently. And your joints will be stiff and easily injured. Inactivity is as much of a health risk as smoking!”
