What's Your Number? How to Measure What Actually Matters for Health and Longevity (Without Spending a Dime)

What if aging didn't have to mean decline? At 60, Dr. Brad Cooper is running a real-world experiment on himself: can he match—or even beat—his marathon and Ironman finish times from over a decade ago, without medications or TRT? In this episode, he lays out the data behind the "1% per year after 40" drop-off, why he's not willing to accept it as inevitable, and the two races that will put the theory to the test—the California International Marathon and Ironman Texas.
