> Once there was a remote mountaintop monastery, nestled high in the clouds above a deep gorge. To reach the monastery, visitors were required to ride in a basket pulled up from the top. One day, halfway up the cliff, a tourist frowned at the condition of the rope. He asked his guide, "How often do they replace this rope, anyway?" The monk answered "We have a large team of monks who continuously monitor the rope using advanced technology. We actually invented the field of reliability analysis to help us keep this rope safe. If we notice anything wrong with the rope, we immediately repair it. The rope is guarded by heavily armed guards to make sure no one sabotages it."
