“Adaptation is one explanation of how a lot of executives stay alive. As the fish in the Silurian rivers began to develop swim bladders in order to live in shoal waters, so American executives have developed certain compensating features. The process can be observed particularly in the big cities where conditions are the most trying. Executives have developed an insensitivity to noise, an uncanny time sense (needed in commuting), and an attunement to the city’s terrifying rhythms. Instead of trying to escape the phenomenon of modern life they fling themselves at it.”
