Get out and do something, it will improve your quality of life. People say that all the time. You'll be more mobile, you won't get tired as quick, you'll look better, you'll sleep better, bladiblablah. Not every one cares about that stuff. Some people don't have much activity to do and are blessed with a fast metabolism, good looks, and a very comfy bed. But what if you are anxious? Or depressed? What if you find yourself angry all the time? Frustrated about things you can't control? This is the part where I talk you into trying to exercise.
