Take a trip back with me to high school English class. In J. D Salinger’s, Catcher in the Rye, Holden Caulfield ponders what happens to the fish when a pond in Central Park freezes over for the winter. As he wonders this aloud in a taxi, the surly cab driver tells him that the fish freeze in the ice, nourishing themselves through their pores. He claims they simply thaw in the spring, continuing as they had prior.
