            To be, or not to be: that is the question:

            Or to take arms against a sea of troubles,
            And by opposing end them? To die: to sleep;
            No more; and by a sleep to say we end
            The heart-ache and the thousand natural shocks That flesh is heir to, 'tis a consummation Devoutly to be wish'd. To die, to sleep;
            To sleep: perchance to dream: ay, there's the rub;
            For in that sleep of death what dreams may come
            When we have shuffled off this mortal coil,
            Must give us pause: there's the respect
            That makes calamity of so long life;
