(NBC) - New research finds exercising your heart as a young adult can benefit your brain in middle age.
A study of almost 3,000 men and women in their 20's found those who had good cardio fitness scored higher on memory and thinking tests 25 years later than those who were less fit.
Those kept exercising and performed better on tests measuring the ability to manage time, plan, and organize, which is a strong predictor of dementia and Alzheimer's disease.
