Here’s a suggestion for filling in the blanks in the passage:

Health and fitness are not just for young people. They are for anybody willing to accept the discipline of a good diet and regular exercise. (1) **As** age, there is a tendency to feel that the body is no longer able to perform. Aches and pains are considered normal. Instead of pushing the body to do (2) **strenuous** activities, activities become limited. Yet example (3) **after** shows us that older people can- and should- (4) **remain** active. Men and women in (5) **their** sixties have run in marathons, races of more than twenty-six miles. Some professional athletes stay competitive (6) **into** their forties and fifties. For most people, simple activities (7) **like** walking and swimming are all that is needed to stay in shape. It’s important to include exercise in your (8) **daily** routine. In winter, (9) **try** push-ups, sit-ups, and other indoor exercises. Of course, such exercises will be of little use if you follow them (10) **with** soda and chips.
