Some did, as they very much do now.
However, most didn't, they lived out their days in Geriatric wards, very traumatic places - my mum worked on one for a few weeks, the demented could be sent out of sight to Victorian asylums in the countryside, now exclusive flats or golf clubs.
Nursing homes were not unheard off, the wealthy used them, there were also Council run ones.
People also died of their ailments, now they live for many years.
Pre war, one of my Mums childhood memories was the stink from her Grans incontinence, no pads, no washing machines, tumble driers or detergents, her own mother could do this because her husband - Naval Officer - was well paid and she didn't need to go out to work.
You, like most people who witter on about the Good ole days have no fucking clue.
