The aging brain resembles the creative brain in several ways. For instance, the aging brain is more distractible and somewhat more disinhibited than the younger brain. Aging brains score better on tests of crystallized IQ and creative brains use crystallized knowledge to make novel and original associations. These changes in the aging brain may make it ideally suited to accomplish work in a number of creative domains. So instead of promoting retirement at age 65, perhaps we as a society should be promoting transition at age 65: transition into a creative field where our growing resource of individuals with aging brains can preserve their wisdom in culturally-valued works of art, music, or writing. In a recent study, psychologist Lynn Hasher and her group at the University of Toronto found that older participants were more distractible than their younger counterparts. However, members of this older, distractible group were also better able to use the distracting information to solve problems presented later in the study. This work, along with other studies on aging and cognition, suggests that the aging brain is characterized by a broadening focus of attention. Numerous studies suggest that highly creative individuals also employ a broadened rather than focused state of attention. This state of widened attention allows the individual to have disparate bits of information in mind at the same time. Combining remote bits of information is the hallmark of the creative idea. Other studies show that certain areas of the prefrontal cortex involved in self-conscious awareness and emotions are thinner in the aging brain. This may correlate with the diminished need to please and impress others, which is a notable characteristic of both aging individuals and creative luminaries. Both older individuals and creative types are more willing to speak their minds and disregard social expectations than are their younger, more conventional counterparts. Finally, intelligence studies indicate that older individuals have access to an increasing store of knowledge gained over a lifetime of learning and experience. Combining bits of knowledge into novel and original ideas is what the creative brain is all about. Thus, having access to the increased internal warehouse of knowledge provides fertile ground for creative activity in the aging brain. Many seniors are already making a mark for themselves in creative fields. Consider Millard Kaufman, who wrote his first novel, the hit book Bowl of Cherries, at age 90. Then there's 93-year-old Lorna Page, who caused waves in Britain with her first novel A Dangerous Weakness. Following in the footsteps of Grandma Moses (who did not take up painting until in her 70s), former patent attorney John Root Hopkins turned to art after retirement and had a showing of his works in the American Visionary Art Museum at age 73. Our expectations of the elderly should be changed. Instead of referring to "the aging problem," we should expect our seniors to be productive throughout the lifespan.
