TL;DR: The explanation of increasing heterogeneity and inequality within aging cohorts is a central concern of the life-course perspective and common ground for demographers, economists, historians, sociologists, and psychologists alike.

TL;DR: These findings suggest that some aspects of the social determinants of health—especially those that can be modeled through studies of direct social interaction in nonhuman animals—have deep evolutionary roots and present new opportunities for studying the emergence of social disparities in health and mortality risk.

TL;DR: How processes of cumulative adversity shape heart attack risk trajectories across the life course is examined, suggesting that future research should consider how processes ofulative adversity initiated in childhood influence health outcomes in older ages.

TL;DR: This paper applied a sociological model of cumulative dis/advantage to the baby-boom cohort to examine whether life course timing differences in educational attainment help explain wage differentials by midlife, finding that advantaged social origins lead to early postsecondary completion of degrees, which, in turn, yield higher wages.

TL;DR: The history, meanings, and uses of these concepts across anthropology, psychology, economics, and sociology are reviewed in this article, where three areas of modern sociology (individual aging, family life cycle, and organizational life cycle) are examined specifically in their treatment of life cycle concepts.
