Prepare a graph that portrays the following story.
"I was conceived on August 5, 1962. When I was born I weighed 8 pounds 3 ounces. During my teen years I was very athletic. It was 1979 when I reached my maximum height of 6 foot 3 inches. Since graduating from college I have had an easy life of sedentary office work, and a very healthy appetite. In 1989 I was encouraged by my doctor to eat sensibly and enter a rigorous exercise program of running and working out."
