A new study by Timothy Salthouse and the Salthouse Cognitive Aging Lab has shown that a normal person’s mental abilities peak at age 22, and then begin to deteriorate at age 27. Apparently previous tests were biased towards middle-agers, and thus inaccurately showed our mental decline much later in life. Brain training can increase mental agility, though not as effectively as physical exercise.
The funny thing to me is, I can clearly remember just how stupid I was at age 22. My brain may have been moving faster, but all it was thinking about was girls, so the added efficiencies were of dubious value. Added to that is the fact that I am now about a bozillion times happier with myself and my life now than I was back then, even if I can’t do pull-ups any more.
I wonder if the Salthouse scientists have any data on whether people are any happier with their big ol’ brain power? Somehow I’m betting Timothy Salthouse is too old to have thought to ask.
