This work investigates how sociocultural environments and individual contexts shape the experience of aging across diverse global populations. The authors, Andrew E. Scharlach and Kazumi Hoshino, utilize a multidisciplinary framework to examine the intersection of biological aging, social policy, and cultural expectations. By synthesizing cross-cultural data, they argue that healthy aging is not merely a physiological outcome but a product of the interaction between personal agency and systemic support structures.
