One day an Indian went to see his doctor. The doctor looked him over and said, "Medicine won't help you. You must have a good rest. Go to a quiet country place for a month, go to bed early, drink milk, walk a lot, and smoke only one cigar  a day." A month later, the Indian came to see the doctor again. "How are you?" said the doctor. "I'm glad to see you again. You look much younger." "Oh, doctor, I feel quite well now," said the Indian, "I had a good rest. I went to bed early. I drank a lot of milk. I walked a lot. You certainly helped me. But you told me to smoke one cigar a day, and that almost  killed me at first. It was not easy to begin smoking at my age." From the story we can guess_.
the Indian was a young man the doctor was a good doctor the Indian would go on smoking the doctor wasn't very careful
