The world is so big, why spend 40 years in a single place?
Lay down roots, be part of a community, have meaningful connections.
My parents live in southern Italy, in the same small town my mother is from and the small town my father is from is like 5-6 km far.
Every time there is some kind of event (eg: somebody’s parents passing away) it so hearth-warming to see people come together and try and be close to people they’ve known all their life (60+ years).
I moved to a large town nowadays for work and i have a bunch of superficial connections, my peers lament pretty much the same.
I can see why somebody would like to stay 40 years in the same place.
As with many things, you can go broad, or you can go deep. Not both. You can go one and then the other.
I expect society is best with a mix of both types of people. It usually is.
