Once upon a time, on a small island, there lived many people. For days, the weather forecaster announced that a fierce storm was approaching that would hit the small island on October 15 at 12:00 noon. Early that morning, most of the inhabitants left the island, that is, all except for a small group of actuaries. You see, each of those actuaries had determined that it would take exactly 5 minutes to cross the bridge. At 11:55, however, there was a traffic jam at the small bridge. At 12:00, the fierce storm came and swallowed up the actuaries.
And then everybody lived happily ever after on time.
