Get a Rope
There is a story about a monastery in Europe perched high on
a cliff several hundred feet in the air. The only way to
reach the monastery was to be suspended in a basket which was
pulled to the top by several monks who pulled and tugged with
all their strength. Obviously the ride up the steep cliff in
that basket was terrifying.
One tourist got exceedingly nervous about half-way up as he
noticed that the rope by which he was suspended was old and
frayed. With trembling voice, he asked the monk who was
riding with him in the basket how often they changed the
The monk thought for a moment and answered brusquely,
"Whenever it breaks."
