We return to the catalogue at the beginning of the first chapter, the things we all find stressful—traffic jams, money worries, overwork, the anxieties of relationships. Few of them are “real” in the sense that that zebra or that lion would understand. In our privileged lives, we are uniquely smart enough to have invented these stressors and uniquely foolish enough to have let them, too often, dominate our lives. Surely we have the potential to be uniquely wise enough to banish their stressful hold.
