The Doctor`s Advice

Mr. Bell felt very bad. Every day he had bad headaches, he…eat and sleep. One of his friends said that Mr. Bell… see doctor Green who always gave his patients good advice. Mr. Bell phoned the doctor and was told to come the next day.

After the doctor had examined Mr. Bell he told the patient that he…go to a village and stay there not less than a month. He also added that Mr. Bell… go to bed early, drink milk, eat a lot of vegetables and fruit and smoke only one cigar a day. “You…follow my advice”, said the doctor, “and in a month you will feel as well as before”. Mr. Bell looked a little surprised when he heard the doctor`s advice and said, “…I ask you?” but the doctor had already invited another patient in and Mr. Bell… to leave not having asked his question.

As you remember Mr. Bell…to come to see the doctor a month later. When the doctor saw him he said: “You look much better now. Has my advice helped you?”

“Thank you, doctor”, said Mr. Bell. “I did everything you had recommended: I went to the country, I ate a lot of fruit and vegetables, drank milk but I … to give up one of your recommendations. You see one cigar a day nearly killed me. It is impossible to begin smoking at my age”.
