Think you know how to avoid overeating? Think again.

Research suggests that choices, like how much to eat during a meal, are often made subconsciously. Trouble is, our brains are hard-wired to mislead us in lots of little ways, which can have a big impact on our diets.

Take the Delboeuf effect, an optical illusion first documented in 1865. It starts with two dots of equal size. But surround one dot with a large circle and the other dot with a small one, and suddenly the second dot looks bigger.

NBC's new drama, Smash, plumbs the drama behind the curtain. The series is the story of a Broadway musical — from the first idea, to auditions, rehearsals and the big premiere.

Theresa Rebeck is the show's creator and executive producer. She's also a screenwriter, playwright and a Broadway veteran — with a hit play "Seminar," that's now on Broadway.

Rebeck tells Weekend Edition host Scott Simon that Smash is a "workplace drama — it's just that the workplace is a musical."

After his second-place finish in the South Carolina primary, Mitt Romney arrived in Florida armed with money and organization. He's used both to stop Newt Gingrich's momentum. With three days until the primary, polls give Romney a solid lead over Gingrich in Florida.

Florida is a big state, but Romney and Gingrich's paths have crossed often this week. There were the two debates, and in Miami, like Gingrich, Romney spoke to the Hispanic Leadership Network Friday.
