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?
Physical hobbies are alive and well, but kinda niche when compared to things like video games or tv/movies. I got into model building a couple years ago, and there are plenty of folks who are into it. I would argue the hobby is bigger than it’s ever been. Same goes for other things like r/c and tabletop gaming.
Also, don’t forget about 3d printing, which would definitely fit as a physical hobby. It also augments the previously mentioned hobbies, as well as many more.
