Mental Activity Maintain Your Brain
keeping the brain active seems to increase its vitality and may build its reserves of brain cells and connections. You could even generate new brain cells.
Low levels of education have been found to be related to a higher risk of Alzheimer’s later in life. This may be due to a lower level of life-long mental stimulation. Put another way, higher levels of education appear to be somewhat protective against Alzheimer’s, possibly because brain cells and their connections are stronger. Well-educated individuals can still get Alzheimer’s, but symptoms may appear later because of this protective effect.
