I suppose it would be mostly practical skills, cooking, fixing things. Usually had to be done by people themselves.
Maybe also mental things like navigating (with or without paper map) and remembering their daily and weekly agendas.
What other things would be a big difference with the people today?
You can still learn where the streets are. Seattle is one of the worst planned cities in America and you can still navigate it by route if you’ve spent twenty years learning it.
