Study: Women's brains appear three years younger than men

But why?

One theory is that hormones might begin shaping brain metabolism at a young age, setting females on a pattern that is more youthful throughout their lives, compared to men.

Scientists hope to find out if metabolic differences in the brain may play a protective role for women, who tend to score better than men on cognitive tests of reason, memory and problem solving in old age.

It "could mean that the reason women don't experience as much cognitive decline in later years is because their brains are effectively younger," said Goyal.
