For much of history, human beings needed to be physically active every day in order to hunt or gather food — or to avoid becoming food themselves. It was an active lifestyle, but one thing it didn't include was any kind of formal exercise.

Daniel Lieberman is a professor in the department of human evolutionary biology at Harvard. He says that the notion of "getting exercise" — movement just for movement's sake — is a relatively new phenomenon in human history.

During the Cold War, the movies we saw from the Eastern bloc were steeped in politics. They critiqued, more or less obliquely, life under communism. More than 30 years later, the Berlin Wall is long gone, but the films from Eastern Europe haven't lost their political edge. These days, they're critical of post-communist societies that remain harsh and oppressive.

In the 1840s, Elizabeth Blackwell was admitted to a U.S. medical school — in part because the male students thought her application was part of an elaborate prank.

If you didn't know what they were about, you'd be forgiven for confusing the striking new movies Promising Young Woman and Pieces of a Woman.

And each one centers on an American woman played by an English actor doing her strongest work in some time.

Iconoclastic humorist Fran Lebowitz used to be known as a writer. Back in the late 1970s and '80s, she released two popular collections of essays featuring her cutting observations and opinions about life. But that part of her career was cut short by a decades-long case of writer's block — now she's known for talking.
