About this episode

Ben Greenfield discusses the balance between health optimization and personal relationships in the pursuit of longevity.

Ben Greenfield has spent decades at the forefront of biohacking, fitness, human performance, and longevity—testing the technologies, tracking the biomarkers, competing at an elite level, and pushing his body to its limits. But after years of relentless self-optimization, he realized something important: living longer means very little if the pursuit of longevity takes you away from the people and experiences you're trying to live longer for. In this conversation, Ben opens up about the side of biohacking we don't talk about enough.
