So at my age (with my grandparents whom passed decades ago) this would be some of the things I'd learn.
How to attach a plow to a tractor, make butter, clean clothes by hand, make a phone call using the party line, make soap, changing the oil in my Studebaker, plant a giant garden, and make homemade sausage. Oh, and how to go to mass EVERY Sunday at the same time...or burn in hell if you missed.
About the only thing on that list that sounds remotely appealing is making homemade sausage.
