In this keynote presentation given at the 2016 Association for Interdisciplinary Studies conference, I considered the field of gerontology from a transdisciplinary perspective. Juxtaposing personal narratives with dominant and alternative discourses on issues of aging, later life, and old age, I explored such questions as: Given the multifaceted, diverse and context-dependent nature of aging phenomena, what might be said to be the defining characteristics of the field of gerontology? Is the common claim that gerontology is "fundamentally interdisciplinary" borne out? How are phenomena of aging--and the aging subject--constructed within (and without) the field? What might a transgressive approach to gerontology that embraces the wild and ultimately untamable lived experience of traveling through the life-course look like?
