““Maybe democracies, maybe all cultures, had life cycles, the same as the humans who comprised them. And maybe there were things cultures could do to extend their lives—the equivalent of exercise and eating right, or, to analogize to what Horton had done, the equivalent of radical surgery—but those things would, in the end, matter only at the margins. Maybe, regardless of the efforts of the exceptional few, the genes hidden and inherent in a culture’s own DNA would dictate a length of years, and make inevitable the onset of sclerosis, and senility, and death, as ineluctably as the Fates cutting the thread of an individual life.””
