In her New York Times article “How to Train the Aging Brain,” Barbara Strauch discusses ways in which people in middle age and beyond can keep their brains strong and nimble. Although there is no lack of evidence that certain brain functions, such as memory, tend to weaken in aging people, scientists now agree that brains not only continue to develop but actually become more capable of discovering big-picture patterns instrumental in problem solving. However, it is essential that aging people practice their brains’ functionality by maintaining and fostering connections between acquired knowledge and today’s changing perceptions of almost every subject.
