Flowers, a shawl and of course, a birthday cake. At 115, Misao Ohkawa is the world's oldest woman. Born in 1898, Ohkawa has lived through the turn of two centuries. She has three children, four grandchildren and six great-grandchildren. And the secret to her longevity? SOUNDBITE: Misao Ohkawa (Japanese): "Sleep well, eat well. Isn't that it?" Wheelchair-bound Ohkawa had her favorite noodle soup and sushi for lunch. Perhaps a recipe for longevity, because she is one of 50,000 centenarians in Japan.
