I read of a study of nuns from the Great Lakes area. All were teachers and to aid in a study of geriatrics, each donated their body to science...They found that these women (ACTIVE teachers well into their 90's) had much denser masses of tissue in their brains.....The reason given was they never stopped learning and teaching as many other studies have found.
The brain can be like a big muscle: exercise makes it last longer
