No one can accuse our colleagues from PopSci's past of not trying. They devoted a large section to tips (with illustrations!) to staying healthy, with assistance from science. Some of those tips, like warnings about diet pills, could be printed today and no one would bat an eye--but others, like chores being enough exercise for "a housewife," maybe not so much. Check out the gallery for them all.
