I mean, not to discount the hard work that your grandparents would have to maintain a self-sustaining life but... it could only work out because they had land available for that. You live in a city and depend on salary because you don't own a parcel of fertile land from which you could be generating enough sustenance for yourself (estimates go from 1/10th to a full acre per person).

An acre is a lot of work.

Many grandparents are too frail to dig enough spuds or work the garden - anecdotally 70s is when limitations often start to really kick in. Grandparents are now trending older?
