Book: Metro 2033: Into darkness

And yet there is a hidden meaning in that maniacal persistence with which man clings to life. Sort of masochistic desire to prolong the agony, balancing between two worlds, the afterlife and the earthly, the desire to extricate himself from the world in a completely hopeless situation, when chances of survival are negligible, and often they simply do not. It is considered that at such moments I remember the most vivid memories, but the head is completely clogged, sticky, chilling the mind with fear. The fear of death. The thought of the imminent demise of the brain squeezes out all others, and out of control the body reacting to the frenzied adrenaline rush, a treacherous defecate.
