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?
Quite common as in, I’ve only met one person here in my life who can only drive automatic. Electric cars being more mainstream means many more people are driving automatic, but if you do your licence in an automatic you are not allowed to drive a manual car. So I’d wager over 99% of people can drive a manual. This is in Belgium btw.
