"Unveiling the Truth Behind Health Fads: VO2 Max, Supplements, Sunlight, and Immortality"

In a podcast episode, guests Steve Magness and Brad Stulberg discuss popular health fads including VO2 max, supplement mania, sunlight, and immortality. Steve Magness explains that while VO2 max measures the maximum amount of oxygen the body can utilize and correlates to decreased mortality, it may not be as revealing as commonly thought, as it doesn't strongly correlate with athletic performance and is often not used in longevity studies. Instead, the speed reached at the end of an exercise test is often used as an indicator of mortality and longevity.
