In this episode of Deep Dive, we explore how overthinking — once a survival advantage that helped our ancestors anticipate dangers — has become a source of modern stress and anxiety. We'll trace the evolutionary roots of rumination, understand why our brains are wired to expect the worst, and uncover strategies to break free from the mental loops that no longer serve us.
