If you're a below-normal VO2 max and you go just to normal, you're getting about a 2.1 increase in life expectancy. If you go below-normal to high-normal, which is about where half the population lies, then you're getting an almost 3-year increase in life expectancy. And then if you go to like more of an elite level, so you're getting into, like, above the upper limit, that's a 5-year increase in life expectancy compared to where you were when you were below normal.
