Women's brains are younger than men's brains

NEW YORK (Reuters Health) – A new study shows that women live longer than men and their mental health is better because their brains are three years younger than their brains.
Participants in the study, which included 84 men and 121 women, underwent positron emission tomography to measure the rate of brain substance exchange, or the flow of oxygen and sugar in the brain.
Like other members of the body, the brain uses sugar as a substance to make it work. The way sugar is eaten says a lot about the age of the brain.
According to a study published at the National Academy of Sciences, participants had ages from the 1920s to the 1980s and women's brains were younger than men's in terms of flow and substance use.
It was found that women's brains were 3.8 years younger than their actual age, compared to men's 2.4 times higher than their actual age.
