What you need is to walk quickly for at least 20 minutes a day” “Doctor, you don’t understand ,” the man said, “I…” “I don’t want to hear any excuses,” the doctor said , “ You must find time for exercise .If you don’t  you will get fat and have health problems when you are older.” “ But I walk every day ,”the man said. “Oh, yes , and I know what kind of walk that is .You walk a few feet to the train station from your house, a few more feet from the station to your office, and a few more feet from your office to a restaurant for lunch and back.
