     A man walked into a doctor's examing room. "Put out your tongue," the doctor said. "OK. You can put your

tongue back now," the doctor said. "It's clear what's wrong with you. You need more exercise." "But, doctor,"

the man said. "I don't think..." 

     "Don't tell me what you think," the doctor said, "I am the doctor, not you. I know what you need. I see

hundreds of people like you. None of them get any exercise. They sit in offices all day and in front of the

television in the evening. What you need is to walk quickly for at least 20 minutes a day." 

     "Doctor, you don't understand," the patient 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 patient said. 

     "Oh, yes, and I know what kind of walking that is. You walk a few meters to the train station from your

house, a few more meters from the station to your office, and a few more meters from your office to a

restaurant for lunch and back." 

     "Please listen to me, doctor!" the patient shouted, getting angry. 

     "I''m a mailman," the patient went on, "and I walk for seven hours every day."
