What were once thought of as one's declining years can now be some of the most rewarding years of life—if you stay healthy and active. And staying healthy and active into your 70s and beyond is easier now than ever before. The two things you can do that will have the most impact on your overall health and quality of life are to eat well and get enough exercise. Even if you haven't always taken the best care of yourself, it is not too late to start. You'll be rewarded with golden years that truly deserve the name.
