Two Bolivian seniors may be the oldest living people on Earth. Zenon and Julia are each allegedly 118 years old, born in the year 1900. If Zenon's age is verified, that would make him the oldest male ever to have lived. Meanwhile, Julia celebrated her big 118 in late October. At a party in her honor, Mama Julia serenaded her admirers on the charango, a kind of lute. Then she tucked in to a healthy serving of one of her favorite foods, cake.
