Home Page Radio Show explores our feelings about our dwellings. Caves, Igloos, tiny  houses, big houses, apartments, capsules -- our nests are important to us. Today's show, "Aging in Place," looks at the phenomenon of more and more people, especially as they age, seeking to stay in their homes. Architect Duo Dickinson and author Leigh Gallagher (End of the Suburbs) and psychotherapist Binnie Klein serve up a free-range discussion on both the macro and the micro level,  with listener phone calls.
