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?
I used to do this when I delivered pizza.bMy phone wasn’t playing well with the GPS because I had put a custom ROM on it that happened to be too much for the thing, plus aging, but the ROM was too good in every other aspect. So I just studied the map on the same computer we clicked through orders on, remembered my route, and in a couple of weeks I didn’t even need to look at the map before going around our zone.
Still helps me navigate cities to this day, even now that I don’t drive at all.
Although living in a post-Soviet country helps with city/road design, making it rather predictable in ways lol
