Some people believe that senior citizens should retire, enjoy their free time, make baby clothes for their grandchildren, and play mah-jong or checkers in the park. If you're eighty years old, you've certainly earned the right to relax and do nothing.

Well, don't tell that to Nathaniel Hendersen. This octogenarian has more energy than a team of adolescent soccer players. And he has been in on the ground floor of more than 200 important inventions in the plastics industry.

What's the secret of his success?

Janice Aldridge, head of Luxury Lifestyles, a customized office furnishings company based in Manhattan, says Hendersen's genius resides in his innovative designs. "Nathaniel is a pioneer in plastics," she reported. "He once told me that he loved imagining solutions to problems and challenges and then making "them" happen in his design studio."

Hendersen's long-time business partner, Olivier Despuits, would agree. He says Hendersen's contributions to plastics design stem from his unique ability to think outside the box. "Nathaniel is one of the most innovative, creative thinkers I have ever known. His designs for ergonomic keyboards transformed the industry almost overnight."

K.L. Wong is a venture capitalist who had the foresight to invest millions in Hendersen's ideas. From his corner office on the thirty-second floor, Wong gazes out the window and contemplates the far-reaching impact of Hendersen's inventions. "You asked me what makes Nathaniel so special. Look out there. He has influenced daily life in thousands of offices. Millions of employees are using equipment for which Nathaniel holds the patent." It was Wong who supplied the infusion of seed capital that catapulted Hendersen's designs into the global spotlight.

What does Hendersen himself think? For him, fame and financial success are almost irrelevant. What matters to him is doing what he enjoys. "I love thinking freely!" he exclaims. "My talent is looking at a product that people use on the job and figuring out how to improve it. Fortunately for me," he adds, "that's a talent with wide applicability. And it's fun!"

With his white hair and bristling eyebrows, the diminutive Hendersen is more energetic than many people half his age. Whatever his secret, he is a vital self-starter whose mission in life is to solve problems through innovative designs. You certainly won't find this creative eighty-year-old playing checkers in the park.
