Individuals living with HIV are considered “elderly” as early as age 50, due to the premature physical ageing they undergo. Given the widespread ageism in western societies, it can be wondered how people living with HIV aged 50 and over (PLHIV50+) perceive their own physical ageing. In this article, based on 38 in-depth interviews conducted with PLHIV50+, the experience of ageing will be explored through three dimensions, namely the physical ageing, the feeling of ageing, and the attitudes toward ageing. Data analysis shows that perceptions about ageing are both negative and positive among PLHIV50+. Indeed, as it is observed in the general population, PLHIV50+ try to distance themselves from age and have sometimes trouble accepting it, but their experience of HIV can however bring a positive value to age, as growing old means being still alive.
