Since she was a little girl, Ashley Caldwell has been in constant motion: jumping out of her crib, tumbling off the couch, leaping down stairs, flipping on a trampoline.

So it seems fitting that now, at 24, Caldwell is the reigning women's world champion in aerials skiing — a sport in which she somersaults and spins through the air, some 60 feet off the ground.

Remember this name: Maame Biney.

The short track speedskater just turned 18; she's not even out of high school. But she is already one of the biggest U.S. names at the Winter Olympics.

Here are a few of the big questions hovering over the Pyeongchang Olympics, about to get underway in South Korea:

  • Which Russian athletes will be allowed to compete?

  • How will the North Korean team fare?

  • Can the United States top its highest number of Winter Olympics medals — the 37 it won eight years ago in Vancouver?

But way up on my own list of burning questions is this: What do these athletes dream about?
