Real experience, meets real science — unpacking what actually improves performance. This episode explores VO2 Max, the objective measure of oxygen consumption and the leading predictor of human longevity.  Oli Patrick explains why this \"Life Number\" is more predictive of lifespan than blood pressure or whether you smoke or not. Data shows that every 1ml/kg increase in VO2 Max adds approximately 45 days to life expectancy.  Spencer also visits a VO2 Max testing centre for the first time in 7 years to see the improvements he's made. Together, they reveal the most effective way to increase VO2 Max; from high-intensity intervals to building a more efficient engine, proving this isn’t just a fitness metric, it’s a measure of how much life you have in the tank.
