Supercentenarian
A supercentenarian (sometimes hyphenated as super-centenarian) is someone who has lived to or passed his or her 110th birthday. This age is achieved by about one in 1,000 centenarians. Anderson et al. concluded that supercentenarians live a life typically free of major age-related diseases until shortly before maximum human lifespan is reached (between 110 and 115 years).
