IstanbulI had a medical in Ankara not long ago. The doctor was a good sort, looked over her spectacles and read out the list: blood pressure all right, weight OK, cholesterol a little high, heart no problem, kidneys no problem Liver? No, nothing — but, Professor Stone, the lungs. Ah, I thought, at 66, and after nearly 50 years of heavy smoking. She told me that I have less lung capacity than would be usual for a man of my age. What is it? I asked. Seventy per cent. What is normal for a man of my age? A twinkle: 73. Thank the Lord for sensible doctors. Obviously if I smoke, there is a problem, but it will not be dispelled by finger-wagging. I am from a generation where nearly everyone smoked, and I have read somewhere that at the time of the Marshall Plan — announced when I was six, in 1947 — we smoked 90 per cent of our dollar earnings.
