Super-centenarians are very rare individuals. They have lived to at least 110 years of age. In the United States, there are approximately 54,000 centenarians (people who are 100 years of age or older). Only about a dozen of these centenarians, however, appear to make it to 110 years old. Worldwide, only about 70 individuals have been verified to be at least 110 years of age or older. Surviving decades longer than their peers — often in far better health — super-centenarians may hold the keys to protection from disease, decline, and early death.
