Perhaps the younger generation doesn't want to spend time with the older generation and thinks they need too much looking after.

This morning (I'm in GMT+8) my father (born 1935) was out for five hours delivering Meals on Wheels to older people that have difficulty cooking for themselves.

Do you mean that modern societies/families no longer take care of their elders within the family?

Wow. My mother was born in 47 and is now wheelchair bound. Barely functioning. It's probably that clean farm life that keeps your father vital at that age.

There's no single one stop comment for the entire planet.

My experience of Japan was that older people stay active longer .. and people like to have purpose and part of that can include looking after each other as people grow old and diminish in function at differing rates.

My experience of parts of some countries such as the UK and the US is that people get fat and relatively inactive some what sooner than I'm used to seeing in here in Australia and elsewhere (Vietnam, Nigeria, etc).

My father had a farming life early on, he's returned to a farm adjacent life in his early 80s, otherwise he's worked largely around minesites as a worker, foreman, manager but has stayed active walking about plants and constantly improving land they've owned by building walls, shovelling tonnes of literal shit for the garden, etc.

Fostering a sense of local community helps ease the changes as people age and there's a place for cross generational interaction in life also: https://www.youtube.com/watch?v=13_rJVvxx_g
