Each of us has to test the limits of his will to survive in this reality.” He leans forward and speaks in grave tones. “Right now, at any time, we could die. It almost makes you lose your sanity.” His pupils quiver with increased intensity. “The fear of dying will make you lose your sanity. But to remain calm and stay in a place where you think you will die, that is the definition of insane, too. You must become insane to survive in combat.”
