I'm reminded of an old story about a man trying to fill a job for driving a stage coach. He asks each applicant how close they can drive to the edge of a cliff without going over. The first few applicants brag about being able to right up to the edge. The job goes to the first to respond "I don't know, I try to stay as far away as possible".
