Health

If any of the 700 athletes in London for the Olympic Games are unlucky enough to get injured, they'll get treated at a state-of-the-art polyclinic situated inside the park. But for the half-million tourists, it's straight to a British hospital for serious ailments requiring medical attention.

If you're an adult, and a relatively healthy one at that, then you've probably been confused in recent years about whether or not you're getting enough vitamin D.

It's Saturday night at the Metropolitan Room, a comedy club in New York City. Host Jimmy Failla is warming up the crowd.

"Where you guys from?" he asks one group in the audience. "Boston? Home of the Red Sox. Personally, we'd prefer you rooted for the Taliban!"

There are 50 or 60 people in the audience, sipping cocktails. Failla has a system. He asks people where they're from. Most are locals. He then hits them with something they can relate to.
