Sumiko Taira, 91, a resident of Ogimi, Okinawa.
CBS News' Daniel Sieberg, who traveled to the Japanese island to try and find out why people live longer there, says, "She sells the 'long life grass' and survives on a modest, government-funded income. We bonded with Sumiko from the moment we started talking with her; she has an infectious laugh and spry gait that betray her 1918 birthdate."
