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?
In Minneapolis, Google maps almost always tells me to leave the parking lot from work, go down the road, and turn left onto a highway during rush hour. No lights.
The way I actually go is to turn 1 block “early” and wait at the stoplight.
Sure, in theory it would be faster to take Google’s way if there’s no traffic, but again – this is when I’m leaving work!
