Women have younger brains


The reason why women tend to outlive men and stay mentally sharper has been investigated. The study showed that  the female brain on an average appear about three years younger. The study enroll ed 121 women and 84 men who underwent PET scans to measure brain metabolism, the flow of oxygen and glucose in their brains.

The subjects ranged from 20’s to 80’s and across those age span , women’s brains appeared metabolically younger than the men’s. On an average it was about 3. 8 years younger than the chronological age compared to men who appeared about 2. 4 years older than their true age. Manu Goyal an assistant professor of Radiology at Washington University School of Medicine said that men start adulthood about three years older than women and that purses throughout life. More work is underway to confirm the implications of the research.
