Yes. If there is a time period you would like to go back, those options exist. Stone Age? Sell everything you own, buy a one way ticket to Africa, and go. Live with a tribe. Middle Ages? Mad rica again, but pick a country with a lot of civil unrest. Try a diamond producing country. Industrial revolution? Move to India. Post revolution? Try China. Want the 50s? For the US, anyway? Go to Germany.
We have AC, plenty of food, and fast cars. I'm happy.
