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?
Well, that’s what I thought too. My family used to, and still does cook almost every meal. Only eating out for special occasions. But asking around with colleagues in the place I live now. It’s surprising how many order takeout or go to a local restaurant for dinner.
I used to know a guy at church who said he didn’t know how to cook and went to the convenience store for every meal.
