A groundbreaking 25-year study has shown that childhood cognitive ability significantly impacts intelligence in older age, with nearly half of cognitive variance persisting across decades. The research tracked participants from childhood through their eighties, linking higher childhood intelligence to improved longevity. This study also revealed significant differences in brain aging, suggesting that genetics and early-life factors profoundly shape cognitive health.
