“Polar exploration is at once the cleanest and most isolated way of having a bad time which has been devised. It is the only form of adventure in which you put on your clothes at Michaelmas and keep them on until Christmas, and save for a layer of natural grease of the body, find them as clean as if they were new. It is more lonely than London, more secluded than any monastery, and the post comes but once a year….Take it all in all, I do not believe anybody on earth has a worse time than an Emperor penguin.” (Apsley Cherry-Garrard, introduction to his book The Worst Journey in the World)
