7 Signs Your Cortisol And Adrenals Are Broken.

In this powerful conversation with Bill Rapier, you’ll discover both the practical and philosophical sides of self-defense, preparedness, and living with vigilance and intention. Bill—a former Navy SEAL and founder of Amtac Shooting—shares not only his deep expertise in firearms, blades, and integrated combatives, but also the mindset that will help you train responsibly and live ready. You’ll learn why carrying tools like firearms and knives is less about aggression and more about having “violence insurance”—a rare but critical safeguard for protecting yourself and others when it truly matters. Whether it’s choosing your first holster, sharpening threat assessment skills, or building resilience, this episode gives you the tools and mindset to elevate your preparedness (while staying true to your values and priorities).
