Thriving on raw eggs, world's oldest person marks 117th birthday in Italy

Emma Morano, thought to be the world's oldest person and the last to be born in the 1800s, celebrated her 117th birthday on Tuesday, still swearing by her diet of two raw eggs a day. Morano was born in November 1899, four years before the Wright brothers first took to the air. Her life has spanned three centuries, two World Wars and over 90 Italian governments.
