There are several possible reasons why my father is in excellent health. First, he is in excellent condition because he has stopped smoking cigarettes. He quit smoking cigarettes since whenever he climbed stairs, he would quickly stop several times and cough loudly. He also has good health as a result of stopping eating the wrong kinds of foods. Third, he is in good physical shape, for he exercises a lot. He swims three times a week at the local gym. In short, my father is in better shape than some of his children are.
