Probing life's changes from childhood to adult. How do we age?

NOW's David Brancaccio sits down with acclaimed director Michael Apted to talk about the surprising human predictors of future-generation education and income both here and in Britain. Apted discusses what he's learned from "49 Up," the seventh chapter of his groundbreaking documentary series that follows the lives of English citizens every seven years. "49 Up" premieres October 9, 2007, on P.O.V . on PBS. 

Also on the show, "Off the Grid," a visit to Decorah, Iowa, where several families are going above and beyond the energy conservation call of duty by producing their own power from renewable sources.
