Old age is perceived as a narrative of decline, recently, an alternative perspective was introduced known as positive aging or Gerotranscendance. This paper examines ageing in Bryony Lavery's A Wedding Story (2000) and Sebastian Barry's Hinterland (2002) through the theory of gerontology. Gerontology in British and Irish modern theatre, according to Giovanna Tallone (2020) and Heather Ingman (2018), is a new category in literary studies and theory. The paper aims to examine the challenges of retaining agency in old age in comparison to the notion of aging as a process of inner harmony further proving that despite the process of ageing being an individualised experience, the commonalities of growing old are universal as depicted in Lavery's and Barry's works.
