Time Magazine makes a good argument that this is the case, at least in the business world. However, I prefer the more honest saying, "80 is the new 80." Anyone not yet there has some wonderful role models to emulate. Certainly when one looks at the accomplishments of today's businessmen, scientists and even enduring rock stars, the retirement age of 65 seems an outmoded and an inappropriate holdover from former times when life stopped sooner. Those who want to retire at 65 and need government help to do so should have it. But for those who want to keep on going, let's start thinking out of the box and not let discriminatory ageism stand in their way.There's Warren Buffett, strumming his ukulele, hosting his Woodstock for capitalists. There's the rich and irascible oil man, T Boone Pickens, trying to save the world with his own TV ads and organization. (And he's not even running for office!) There's Bruce Springsteen whose energy still makes my blood pump. Not to mention Neil Diamond, 67, Mick Jagger, 64, and Tina Turner, 68, who are still filling arenas. And 82 year-old Tony Bennet who has come back from retirement stronger than ever. So, dear FiftyAndFurthermores, think about what you want as you sage. As many Silver Celebrities and everyday folk have shown, the future can be what you make it, at fifty OR at eighty.
