The other day a friend of mine emailed me the link to an article that began with the words: “People of a certain age (and we know who we are) . . .” I laughed out loud. What does that really mean, “People of a certain age?” Hopefully, everyone knows how old he or she is—even though he or she simply may not want to concentrate on a “number.” Personally, I’m concentrating on staying abreast of current research and doing everything within my power to retain optimum brain function. Some studies show that memory accuracy and speed start slipping about age 25 brain and just continue downhill from there. Well, maybe so. However, there are many studies that have shown reversal of memory deficits in some brains when their owner gets serious about obtaining challenging mental stimulation every day with brain aerobic exercises. So what did the article say?
