In this episode, The Old Dogs ramble about some of the things we've come to appreciate that seem to lengthen our lives. We report on a major infestation of Peacocks in affluent Houston neighborhoods. Paul tries to stump the older Old Dog again, with mixed results, again. And we offer the New York Times opinion on the seven keys to longevity. The Old Dogs conversation is the second part of our fascinating chat with Susan Lieberman, whose new book, In the Country of Old, offers a fresh way of approaching the state of being old.
