Dan Buettner spent many years researching "blue zones" in different parts of the world. Blue zones are areas where a surprisingly large percentage of the population lives to an old age in relatively good health. These zones include Okinawa, Sardinia, Nicoya, Ikaria, Singapore, and Loma Linda, California. He discovered four common denominators in the lifestyles of these long-lived people, two of which are obvious to most of us, exercise and a healthy diet, and two that may be less obvious, a sense of purpose in life and good relationships with family and friends. In this issue of Sunshine Sharing, we'll talk about some secrets to a longer life and some supplements with anti-aging effects.
