Jack Green is 75 years old. He is not in good condition. "I think I'm ill," he tells his wife, "I feel awful. I've got a headache and I don't feel like eating." "You've put on a lot of weight recently. You should see the doctor," his wife says, "ask him how to lose weight. It's not good for your health." "OK," says Jack. He goes to see a doctor. The doctor checks his heart and weighs him. Then he says, "You are too heavy. You need to do some excercise to lose about 30 kilograms. Run two miles a day for the next 100 days. Then call and tell me your weight." A week later, the doctor receives a call from Jack. "Doctor, I ran two miles every day and I feel much better. But I have a new problem."
