INTRODUCTION

Does Your Brain Need Beefing Up? The human brain is one of the most complex organisms known. When working at optimum levels, it can process loads of data as quickly as a computer. Although a computer’s hard drive can ultimately store much more data, our brains can store “data” in ways that a computer never could— instantly recalling how crème brûlée smells, feels, and tastes when this dessert is mentioned. Unfortunately the brain doesn’t always remain working at optimum levels . . . unless you work on it! More and more, scientific evidence is proving that our minds don’t have to deteriorate as they age. There are preventive measures we can take that will significantly increase the probability of staying mentally and physically fit throughout our lives. This is good news of course, because mental fitness and agility translate to an enhanced quality of life. Physical exercise, good nutrition, social connection with others, and mental stimulation all play important roles in ensuring that our brains remain sharp and agile at any age. Scientists the world over have been doing research for decades on how some people can stay “with it” while others cannot. The Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study, funded by the National Institutes of Health, demonstrated recently that older adults could improve their cognitive abilities with proper training and that some of these gains could be maintained several years later. In this experiment conducted by a number of researchers, more than 2,800 adults aged 65 to 94 received training in memory, reasoning, or processing speed. After about ten hours of training, each group improved significantly in the area in which they were trained. Even five years later subjects maintained many of their improvements. Research on the physical results of thinking hard—as one is bound to do when solving a puzzle—has shown that just using the brain actually expands the links that interconnect brain cells. The more we think, the better our brains function . . .
