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?
Recently I have started having to ask hours before a plan is meant to execute, whether the other parties are still attending. Three times out of four I’ve been cancelled on - forgot, too busy, whatever the reasons were.

Basically, those people were not going with you. I wouldn’t consider them your friends. Friends would at least tell you they are bailing so you don’t go
