  "Thank you very much," said old John, " I will do everything you say."
  A month later old John came to the doctor again. " Well, I'm glad to see you. You look much younger." Said the doctor.
  "Oh , doctor," said old John, "I feel quite well now. I had a good rest. I went to bed early, I drank a lot of milk, and I walks a lot. Your advice certainly helped me.
