We've got another piece up on NPR's Morning Edition today. It's all about Agatha Christie, the so-called "Nun Study," and what our writing can tell us about our brains. You can listen to the piece online and find a lot more information about the studies right HERE. (Make sure to check out the audio slideshow featuring Sister Alberta Sheridan.) And if you haven't heard it already, listen to our podcast of the story: Vanishing Words.
