Welcome to the bat cave. No, we're not talking about the secret headquarters of a superhero.

This is Gomantong — an ancient cave carved out of 20 million-year-old limestone in the middle of the Borneo rain forest in Malaysia. It's part of a vast network of tunnels and caverns. And it's the perfect hideout for bats.

Most of us suffer back pain at some point in our lives. In fact, it's one of the most common reasons people go to the doctor. Many of us also probably reach for medication. Now, new guidelines from the American College of Physicians say try exercise, yoga, or massage first.

Jan 17, 2017

"People keep asking me, how close are we to going off the cliff," says Dr. James Johnson, professor of infectious diseases medicine at the University of Minnesota.
