Anger feels endless when it arrives-face flushed, chest tight, words rushing to your tongue before reason can intervene. But neuroscience reveals something astonishing: the chemistry of rage is self-limiting. If left alone, it burns through the body in just ninety seconds. The problem is not the surge-it is what we do to keep restarting it.The 90-Second Caveman is a science-driven, clear-eyed exploration of anger's biology and how to live sanely with it. Drawing from cutting-edge neuroscience, psychology, and real-world case studies, this book dismantles myths about fury and replaces them with practical, evidence-based strategies. You'll learn why your amygdala hijacks you before you can think, how cortisol keeps anger simmering long after the initial spike, and why venting makes rage stronger instead of weaker. More importantly, you'll discover how to ride out those ninety seconds without fueling them into ninety minutes-or ninety years-of bitterness.This book offers not quick fixes but durable frameworks. You'll explore the mismatch between ancient survival wiring and modern triggers, from traffic jams to passive-aggressive emails. You'll understand how lack of sleep, hunger, cultural scripts, and relationship dynamics magnify anger beyond biology's intent. Through humor, vivid explanation, and uncompromising clarity, 90 Second Rage Proof reveals how to: Recognize the physical signals of an amygdala hijack before they control your behaviorPractice the "waiting game" that prevents regrettable words and actionsUse breathing, movement, and mindfulness without gimmicks or mysticismSee through thought loops and the "angry narrator" in your headApply the science of the ninety-second surge to relationships, parenting, work, and daily frustrationsReframe forgiveness not as moral sainthood but as a biochemical resetThe message is liberating: anger is not endless. It is renewable only if you keep renewing it. The surge is inevitable, but enslavement to it is not.With a tone that is analytical, direct, and sometimes darkly funny, The 90-Second Caveman blends rigorous science with relatable stories to show you that biology is not destiny. Anger does not define you; it is simply a wave that passes if you let it. Ninety seconds of patience can change everything.If you want to stop being hijacked by your own nervous system and start living with clarity instead of chaos, this book is your manual.
