One silly question I simply can't stand is "How do you feel？" Usually the question is asked of a man in action—a man on the walking along the street, or busily working at his desk. So what do you expect him to say？ He'll probably say, "Fine, I'm all right", but you've put a bug in his ear—maybe now he's not sure. If you are a good friend, you may have seen something in his face, or his walk, that he overlooked that morning. It starts him worrying a little.
Every question has its time and place. It's perfectly acceptable, for instance, to ask "How do you feel？" if you are visiting a close friend in the hospital. When George Bernard Shaw, the famous writer of plays was in his eighties, someone asked him "How do you feel？" Shaw put him in his place. "When you reach my age", he said, "either you feel all right or you are dead".
