One silly question I simply can’t understand is "How do you feel?" Usually the question I asked of a man’s action-a man on the go, 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(忽略)that morning. It starts him worrying a little. First thing you know, he looks in a mirror to see if everything is all right, while you go merrily on your way asking someone else. "How do you feel?"

Every question has its time and place. It’s perfectly acceptable, for example, to ask "How do you feel?" if you’re visiting a close friend in hospital. But if the fellow is walking on both legs, hurrying take a train, or sitting at his desk working, it’s no time to ask him that silly question.

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’re dead."
