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?
Meeting up with people, no phone. You arrange a place and a time, and you show up, if the other person isn’t there… You wait.
It was super important not to leave people hanging
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.
When was I meant to find out? When I called you asking how far away you are, only to find you’re not coming at all?
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
