"Look in the mirror. The face that pins you with its double gaze reveals a chastening secret. You are looking into a predator's eyes. Most predators have eyes set right on the front of their heads, so they can use binocular vision to sight and track their prey. ... Prey, on the other hand, have eyes at the sides of their heads, because what they really need is peripheral vision, so they can tell when something is sneaking up behind them. Something like us."
