Absent's post made me think about the recently built Assisted Care Home my mother was in before she went into a Nursing Home.
She had a brand new, well appointed one bedroomed flat. Some of the even larger flats had two bedrooms even though there was only one resident. Some were privately owned but most were rented from our local Housing Association - all by elderly people.
Referring to it as a ghetto would not be wide of the mark. I remember my younger daughter and I having a discussion about the complete waste of facilities. A library....empty, function room with large flat screen telly....empty, courtyard garden....unused, a shop that only opened two days a week due to lack of support etc., etc.,
I know from talking to some of the elderly residents that they preferred the old building (which was demolished) where all the flats were grouped around courtyards or meeting places. They would leave their doors open as it was all on ground floor level. They didn't want to be stuck up on the third floor dependant on a lift.
So....Surely a mix of young and old could work in a complex where there is a supermarket only a five minute walk away, primary and secondary schools around the corner, a bus service into larger towns and GP surgery nearby. It would be lovely to turn the clock back to when communities took care of their own but that's unlikely to happen when people are pigeon holed and young families are unable to find or afford their own homes.
