One-hundred-sixteen-year-old Maria Esther de Capovilla died on Sunday, less than a year after Guinness World Records had verified her birthday—Sept. 14, 1889—and named her the world's oldest living person. How'd they know how old she was?Well, duh. They sliced her open and counted the rings. Don't you know anything?
(What amazes me is that she lasted almost a year afterward.)
