Welcome to R2R Dub! Normally I'd say to hang out here and pick up some knowledge from the fine folks that frequent this forum, but in your case I think you'll often be the one sharing the knowledge with us young'ns.
If ever I get access to a time machine, I think this is the first thing I would do, take what limited knowledge I have now, go back 30 years just to see how people managed to keep things alive before all the tech and science we take for granted now.
