Some contrarians out there bemoan the custom of the year-end review. But not Takeaway host Celeste Headlee. She picks up all the "best whatever of the year" issues on the newsstands, clicks through all the year-in-pictures slideshows, and makes new year's resolutions. She loves the changing over of the years, and is thrilled to share her favorite moments of 2011, from the Arab Spring to some newly discovered planets to the end of the world that never quite happened.
Kenneth C. Davis, author of "Don't Know Much About History," talks with Celeste about how history will remember 2011.
