The Rope to Monastery

A monastery was perched high on a cliff and the only way to reach it was to ride in a basket which was hauled to the top by several monks. Obviously, the ride up the steep cliff in the basket was terrifying. One visitor got exceedingly nervous. About halfway up he noticed that the rope by which he was suspended was old and fraying. With a trembling voice, he asked the monk who was riding with him how often they changed the rope. The monk thought for a moment and answered, "Whenever it breaks."
