The document discusses research on the relationship between aging and creative productivity. It finds: 1) At the aggregate level, creative productivity typically follows a curve of rapid rise, a single peak, and gradual decline with age. 2) However, there is significant individual variability, and the age decrement is more unpredictable at the individual level and influenced by other intrinsic and extrinsic factors. 3) Late-life creative productivity is still possible, as the age decrement may be less due to aging itself and more to other influences.
