Herb Hauser was the best 90-year-old tennis player on the planet when we went one-on-one with him. He was active, had a great sense of humor, and the love of a wonderful woman. His message: "Get off the couch. Have some fun. Take some chances."

Lucy Dettmer is such a great tennis player; she receives free rackets, strings and shoes from a corporate sponsor. The 86-year-old Masters Tennis has even played against Regis Philbin.
