Two of the oldest people in the world have died on the same day. Mary Josephine Ray, who was certified as the oldest person living in the United States, died on Sunday at the age of 114 years, 294 days. She died at a nursing home in Westmoreland but was active until about two weeks before her death, her granddaughter Katherine Ray said. She just enjoyed life. She never thought of dying at all,' Katherine Ray said. 'She was planning for her birthday party.' Ray died just hours before Daisey Bailey, who was 113 years, 342 days, said L. Stephen Coles, a director of the Gerontology Research Group, which tracks and studies old people and certifies those 110 or older, called supercentenarians.
