In this episode, Brent discusses chronic inflammation with Dr. John Wherry, one of the world's leading immunologists. The conversation unpacks the emerging science of chronic inflammation, why more medical testing isn't always better, the surprising connection between vaccines and brain health, and how decades of immune research are paving the way for more personalized medicine. Along the way, Wherry explains why sleep, exercise, and nutrition remain the foundation of a healthy immune system, where technologies like blood biomarkers may eventually fit into preventive care, and why the most exciting breakthroughs in immunology are still on the horizon. He's a wonderful guest, hope you enjoy.
