INTRODUCTION: Aging is universal, yet the pace of its decline varies markedly among, and even within, individuals. Understanding the molecular basis of this aging heterogeneity—and how it is shaped by socioenvironmental conditions—is a critical challenge in geroscience, essential for identifying early vulnerabilities and factors contributing to disparities in health span and lifespan. RATIONALE: Early life adversity (ELA) is linked to age- related diseases and reduced lifespan in humans and other social mammals, but how early exposures shape aging across individuals and tissues remains unclear. …
