If sheep do not have the constant care of a shepherd, they will go the wrong way, unaware of the dangers at hand. They have been known to nibble themselves right off the side of a mountain..... And so, because sheep are sheep, they need shepherds to care for them. The welfare of sheep depends solely upon the care they get from their shepherd. Therefore, the better the shepherd, the healthier the sheep.
