Book excerpt: Age as Disease explores the foundations of gerontology as a discipline to examine the ways contemporary society constructs old age as a disease-state. Framed throughout as ‘gerontological hygeine’, this book examines contemporary regimes, strategies and treatment protocols deployed throughout Australia, the United States, and the United Kingdom. The book deploys critical cultural theories such as biopolitics, somatechnics, ethics, and governmentality to examine how anti-aging technologies operate to problematise the aging body as always-already diseased, and how these come to constitute a movement of abolition, named here as ‘gerontological hygiene’.
