Actually, I've got it - the direct and evidenced connection. In order to have a safe anchor, you need 2 bolts, and when 2 bolts love each other very much, they have little baby bolts. Without the introduction of new bolts to add genetic diversity to the population, we will end up with inbred mutant bolts that will take over any surface without cracks in the rock until the cliff is so heavy with bolts that it all falls down. The End. |
