Exercise

Move. As much as you can, as fast as you can, for as long as you can. No more. No less. Sweat. Breathe very deeply. It makes you feel good. It's not hard labor.

Before you ask them to go the extra mile out on the street. No weight machine necessary. Just a featherweight resistance tube.

Actually, let's let a computer at the National Institutes of Health do the math for you. Plug in your age, weight, height and a few other things. Press Play. A second later, you have the answer: Slower. So what's the question?
