the problem of the igloo itself was much greater. For Freuchen began to notice that the walls of his little shelter were gradually closing in on him Because of the particular weather conditions outside, his breath was literally freezing to the walls, and with each breath the walls became that much thicker, the igloo became that much smaller, until eventually there was almost no room left for his body. It is surely a frightening thing, to imagine breathing yourself into a coffin of ice, and to my mind considerably more compelling than, say, The Pit and the Pendulum by Poe. For in this case it is the man himself who is the agent of his own destruction, and further, the instrument of that destruction is the very thing he needs to keep himself alive. For surely a man cannot live if he does not breathe. But at the same time, he will not live if he does breathe.
