Mrswhitewash in my experience, all my friends who went to uni moved elsewhere to in laws / their parents.
Non receive any 'free childcare' apart from x2 Max per year of overnight at the weekend if they've got a wedding or anniversary.
I think the 'regular free weekly childcare provided by GP' is a myth outside of working class families who live very near each other.
Also as an aside all the great grandparents mentioned above (some alive some recently died - all born around 1920-1930) lived alone, managed own homes with paid for help. Only help from my parents / IL ovassional drive to hospital.
So no, I don't agree that 'many people get dementia require long term care' as this does not apply to any of the total of 8 great grandparents here.
I think it's a cliche people say to make them feel better about 60-70y taking family wealth and not distributing it.
