A visually stunning National Geographic documentary series in which Chris Hemsworth works alongside world-class scientists, doctors, and experts to explore the science of longevity through a series of extraordinary physical and mental challenges covering stress, fasting, cold exposure, strength, memory, and mortality. Beautifully filmed and gripping to watch, it brings cutting-edge health science to life in a way that feels genuinely motivating rather than overwhelming, leaving you thinking seriously about your own health potential and what is possible at any age. Recommended for anyone curious about longevity and lifestyle medicine who wants to be inspired as much as informed.
