A little while ago, I went to see a Harley Street surgeon about a breathing disorder. (mine, not his.) "I see," breathed the surgeon in his special calm voice, as he scanned the notes which had been sent on from my GP, "that you are a journalist and broadcaster." I must advise you, with your condition, to avoid taking cocaine." But I don't!" I protested. The surgeon raised a special surgical eyebrow, and returned to his notes.
