Very little research focusing specifically on bisexual ageing has been conducted anywhere in the world. Ageing is a lifelong process so there is a small literature on the ageing experiences of bisexual people in their thirties, forties, fifties and early sixties, which this chapter overviews. However, there is an almost complete knowledge gap about bisexual people in their seventies, eighties or older. Studies of LGBTQ ageing more generally seldom offer meaningful information about the experiences of bisexual people as they grow older.
