Dr. Thomas O’Grady, an economist, walks listeners through rethinking retirement and prospering long after 50. Life expectancy is approaching 90. Many active years ahead offer opportunities for pursuing new careers and interests. “Approach the new reality from an optimistic standpoint,” economist O’Grady advises. “You can learn and do new things. Think of the kinds of careers that will be available in the future. You may be doing something full-time now and decide on some new or other work you will do on the side. Or, you may decide to start your own business.”
