Study finds women’s brains appear to be three years younger than men's

A recent study could help explain why, as the years go by, women tend to stay mentally sharper than men.

Washington University School of Medicine in St. Louis reports researchers found that "women's brains appear to be about three years younger than men's of the same chronological age, metabolically speaking."

The study, which focused on how the brain uses sugar, involved 121 women and 84 men ranging in age from 20 to 82 years.
