The Worst Journey in the World 

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 the natural grease of the body, find them as clean as though they were new. It is more lonely than London, more secluded than any monastery, and the post comes but once a year. As men will compare the hardships of France, Palestine, or Mesopotamia, so it would be interesting to contrast the rival claims of the Antarctic as a medium of discomfort. A member of Campbell's party tells me that the trenches at Ypres were a comparative picnic. But until somebody can evolve a standard of endurance I am unable to see how it can be done. Take it all in all, I do not believe anybody on earth has a worse time than an Emperor penguin.
