Today, I'm excited to bring back the always thought-provoking Joel Greene, author of "The Immunity Code" and "The Way," for a fresh conversation on why true longevity is about so much more than how much muscle you have or the latest diet trend you're following. Joel Greene opens up about the hard lessons he's learned from decades of self-experimentation and reveals why chasing that ideal gym physique might actually backfire as you age.
