In "What Doesn't Kill Us," Scott Carney takes readers on an exhilarating journey back to our evolutionary roots, challenging the modern comforts that have made us physically vulnerable and disconnected from the natural world. With compelling storytelling, Carney explores how our ancestors thrived in harsh environments, relying on their wits and physical resilience. Today's sedentary lifestyle, dominated by climate-controlled spaces and convenience, has not only weakened our bodies but also led to a spike in autoimmune diseases and obesity. Carney argues that embracing our discomfort, through exposure to the natural elements like cold and heat, can rekindle our lost evolutionary strength and improve our health in unimaginable ways. Through a blend of personal narrative, cutting-edge science, and enthralling encounters with extreme athletes and fitness gurus like Wim Hof, known for his extraordinary ability to withstand freezing temperatures, Carney paints a vivid picture of human potential. "What Doesn't Kill Us" is not just a book about survival; it's a revolutionary guide that promises to transform our bodies and minds by challenging us to rethink our relationship with the environment. As Carney embarks on a record-setting climb up Mt. Kilimanjaro in nothing but shorts, he offers a compelling testament to the power of pushing our limits and reconnecting with the natural forces that shaped our ancient ancestors. This book is an invitation to unleash our inherent resilience by stepping out of our comfort zone and embracing the transformative power of the elements.
