ВОТ ТЕКСТ

Once an old gentleman came to consult a doctor.
"What do you complain of?" asked the doctor.
"You see, doctor, my nervous system is in a bad state. I have a heartache, often headache and my sleep isn’t good. Sometimes I cannot sleep all night long."
The doctor examined the patient very carefully and said:
"Your treatment will be very simple, in other words it will be a rest-cure. You should go to a quiet place in the village for a month and have an active rest there: get up early, do morning exercises, have breakfast and go for a walk. You should walk much, go to the forest for fresh air, eat much fruit and vegetables and drink milk before going to bed. And you can smoke one cigarette a day."
A month later the gentleman came to see the doctor again.
"How are you?" asked the doctor.
"I am quite well now," answered the patient "I’ve done everything that you recommended me, doctor. I strictly followed all your orders. I walked much, ate much fruit and vegetables and drank milk before going to sleep. But one cigarette a day almost killed me."
"But why?" asked the doctor.
"It’s not a joke to begin smoking at my age. I had never smoked before." answered the gentleman.
