“The brain is evolutionarily hard-wired to do its best daydreaming only when it senses that it is safe to do so – when, in short, it is relaxed. In Kounios’s words, “The relaxation phase is crucial.5 That’s why so many insights happen during warm showers.” Or during Sunday afternoon walks on Glasgow Green, when the idea of a separate condenser seems to have excited the aSTG in the skull of James Watt. Eureka indeed.”
