For most of American history, surviving a city summer wasn't a matter of comfort — it was a genuine test of endurance, and sometimes survival.

A grocery run in 1960 meant choosing from roughly 1,500 products in a store that had never heard of kiwi fruit, year-round strawberries, or a dozen varieties of olive oil.

A Heart Attack in 1955 Was Almost Always the End. Today, Most People Walk Out of the Hospital.

Before the Highway Existed, Driving Across America Was a Survival Exercise

Before Google, Answering a Simple Question Could Wreck Your Entire Afternoon
