The world's oldest person, Japanese woman Kama Chinen, has died. According to Guinness World Records, Ms. Chinen died a week short of her 115th birthday after a life spanning three centuries. Her reign as the oldest living person began on the death of US woman Gertrude Baines, who died last September. Ms Chinen's death hands the title of world's oldest person to Eugenie Blanchard, a 114-year-old French woman living on the Caribbean island of Guadeloupe.
