I’ve learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel. –Maya Angelou

There are few sure things in life.  We are constantly bombarded by messages about magical superfoods, diets, therapies and so forth.  While some of these remedies certainly have merit, there is no other remedy - none - that has demonstrated the power of exercise in improving health and function, and increasing longevity.  No one lives forever; but physical activity will help ensure that your later years are the best quality possible.
