I've been looking on Rightmove and some properties come up which are only for over 55s. I'm 56 but weirdly don't think of myself as their demographic. Perhaps I am but I don't know of anyone in my age range who has availed themselves of one of these properties. On the contrary, as a fit and healthy (touch wood) empty nester, pre-lockdown I was considering a place in central London, and definitely not in a block aimed at older people.
Could it be that soon there will be a shift due to the ageing population, and these places will start being marketed towards, say, over 70s instead? I don't feel offended by it in any way - especially as often these places seem very good value!
