An ironworker nonchalantly walked the narrow beam fifteen floors above the city sidewalk. Though strong winds were blowing a heavy rain, the worker showed no fear whatever. When he came down to the sidewalk, a man who had been watching him from ground level went over to him and said, “I was really impressed watching you up there. You were so calm. How did you get a job like this?” “Well, as a matter of fact,” replied the ironworker, “I used to drive a school bus, until my nerves gave out.”
