"Good God," I said to myself, "and this is merely New York! What must Mexico be like!" I supposed that I was experiencing normal conditions, whereas in point of fact I had landed at the climax of a heat wave which killed about a hundred people a day while it lasted.

In any case, that principle means we should probably refrain from reading HN too.
