In this episode the old dogs ramble about passing along our infinite wisdom to our heirs. We share fascinating – and relevant – information about the role of older elephants. We caution about the overzealous use of fly swatters. We study the new social phenomenon of walk-tailing, we tell the tale of a retired cop who finally got his man. And we mourn the passing of one of our boyhood heroines, Diana Rigg. The Old Dogs conversation is with David Henry: an international authority on what’s going on in the wild lands above the Artic Circle.
