> I'm 40, so perhaps things have changed a bit more than those younger than me, but I can still make most food from scratch ingredients, have no issues sleeping outside in the cold, and can iron and mend my own clothes. I'm only a few years younger than you, and I can do all those things too. I think you likely vastly underestimate the gulf between the old-timey things you know how to do, and the old-timey things you'd be forced to do in 1915 -- the Rumsfeldian unknown unknowns.
