Contributing to both ageing research and queer-feminist scholarship, this article introduces feminist philosopher Margrit Shildrick’s queer notion of the monstrous to the subject of ageing and the issue of dealing with frailty within ageing research. The monstrous, as a norm-critical notion, takes as its point of departure that we are always already monstrous, meaning that the western ideal of well-ordered, independent, unleaky, rational embodied subjects is impossible to achieve. From this starting point the normalizing and optimizing strategies of ageing research (...) – here exemplified through the concept of successful ageing and the treatment of Alzheimer’s disease – can be problematized. The notion of the monstrous instead suggests a view on ageing and ‘monstrous’ embodiment which provides room for other, different ways of being recognized as an embodied subject, and for dealing with difference, vulnerability and frailty.
