It’s saying 38 is the maximum lifespan of a human, determined by genetics, and the only reason we can live past 38 is due to unnatural interventions ie medicine
It’s saying 38 is the maximum lifespan predicted by their model—but it also says their model has an R2 of 0.76, meaning it only accounts for about 76% of the actual measured variation. And then they mention other factors that could account for the remaining 24% of the variation, including post-reproductive-age lifespan.
