Bear Grylls joins Tim Gray for a wide-ranging conversation about resilience, longevity, mental strength, nutrition, family, faith and why modern society has become too comfortable.
From surviving a devastating parachuting accident that broke his back in three places to climbing Mount Everest just two years later, Bear shares the mindset that has guided him through decades of adventure, television and life.
They explore why anxiety never really disappears, why doing difficult things every day builds inner resilience, why natural living beats perfection, and how health is ultimately about building a life worth living—not simply extending it.
In this episode, we explore:
➡︎ How breaking his back became the defining moment of his life Bear reflects on the accident that ended his military career, the loss of identity that followed, and how setting the goal of climbing Everest became the foundation of his recovery.
➡︎ Why “Do Your Best” matters more than being the best The Scout motto has become Bear’s philosophy for life. Rather than chasing perfection, he explains why showing up, embracing vulnerability and simply doing your best creates stronger, happier people.
➡︎ Why discomfort is the greatest training tool From cold water and parachuting to public speaking and difficult conversations, Bear explains why deliberately seeking discomfort strengthens both the body and mind for life’s inevitable challenges.
➡︎ The diet journey that completely changed his health Bear discusses why his family moved from veganism toward an animal-based diet, the lessons he learned along the way, why he prioritises nutrient-dense whole foods, and why avoiding ultra-processed food remains one of his biggest health principles.
➡︎ Why community may be the greatest longevity hack Tim and Bear discuss how meaningful relationships consistently outperform diet and exercise in longevity research, and why loneliness remains one of the biggest threats to long-term health.
➡︎ Faith, family and building a meaningful life Bear shares why faith has remained one of the most important foundations of his life, how family influences every major decision he makes, and why purpose ultimately matters more than performance.
Bear Grylls is one of the world’s most recognised adventurers, television presenters and bestselling authors. After serving in the British Army’s Special Air Service Reserve, a parachuting accident left him with three broken vertebrae. Just two years later he became one of the youngest Britons to summit Mount Everest.
Over the past two decades, Bear has inspired millions through television series including Man vs Wild and Running Wild with Bear Grylls, while championing resilience, outdoor adventure, leadership and living courageously. He is also Chief Ambassador to The Scouts and founder of Modern Savage, a family-led wellness company focused on nutrient-dense whole-food supplementation.

A huge thank you to Modern Savage for sponsoring this episode.
Modern Savage was created by Bear Grylls and his family after years of exploring what genuinely supports strength, resilience and long-term health. Rather than creating dozens of different supplements, they focused on a simple range built around nutrient-dense whole foods and evidence-backed ingredients.
Their products combine grass-fed bovine organs with ingredients like colostrum, electrolytes, creatine, vitamin D3, magnesium and zinc to help support energy, recovery and everyday performance. As Bear explains in this episode, supplements should complement—not replace—the foundations of health: real food, movement, nature, community and purpose.
