Answer 1

Think of your body like a car. The longer you operate that car the more it wears down. As we age important systems within your body suffer from your lifestyle and just the passing of time, regardless. We aren’t cars though, we can’t replace our systems and that’s why its so important to take care of them so they run well for as long as they can muster.
