In this eye-opening episode, Harvard evolutionary biologist Daniel Lieberman explains why our modern approach to health is often at odds with our biological history. We’ve been told that sitting is "the new smoking" and that we must sleep exactly 8 hours a night, but the science of human evolution tells a different story. By studying native tribes and hunter-gatherer societies, Lieberman discovered that many of our "natural" health standards are actually modern inventions.

We dive deep into the concept of Evolutionary Medicine, exploring the "Use It or Lose It" principle. Lieberman reveals why we didn't evolve to "exercise" in gyms, but to be physically active for survival. He explains the critical importance of strength training as we age to prevent sarcopenia (muscle loss) and why "active retirement" is a biological necessity. From the truth behind the 10,000 steps rule to how physical activity repairs our DNA and brain, this conversation provides a roadmap for slowing senescence and preventing 74% of modern diseases. If you want to understand how your body was truly meant to live, this is a must-watch.
