This chapter explores the critical intersections between ageing, human development, and the life course as precarious forms of life. The first part reviews the literature on global precarity and the endangerment of liveability in relation to ageing populations, with a focus on neoliberal strategies that naturalise and individualise risky life-course trajectories and health crises. The second part examines selected figures of the obese child, unstable adolescent, despairing mid-lifer, and cognitively impaired older adult as examples of crisis-laden personifications of social problems. Data are drawn from historical texts, popular images and professional knowledges. Conclusions revisit the work of Butler and Foucault to raise questions about current models of resilience and the possibilities of resistance and living differently.
