For the Indigenous A'uwẽ (Xavante) people in the tropical savannas of Brazil, special forms of intimate and antagonistic social relations, camaraderie, suffering, and engagement with the environment are fundamental aspects of community well-being. In this work, the author transparently presents ethnographic insights from long-term anthropological fieldwork in two A'uwẽ communities, addressing how distinctive constructions of age organization contribute to social well-being in an era of major ecological, economic, and sociocultural change.
