 If that bus driver is old and you know he fell asleep at the wheel before, are you going to sign him up to drive a bus for the next four years back and forth from Baltimore to New York when you're starting to see the decline? Or are you going to say, man, you did a great job getting people back and forth safely, but now it's time for someone else to do it because we don't know that you can safely navigate it for a four-year contract.
