Experts predict that the number of centenarians - people who live to be at least 100 years old - will continue to rise in the coming decades.

Sister André, a French Catholic nun born Lucile Randon, who was the world's oldest living person, recently died at the age of 118. Now the two oldest living people are believed to be María Branyas Morera, a 115-year-old Spanish woman born in the United States, and Fusa Tatsumi, who lives in Osaka, Japan, who is also 115 but 52 days younger than Morera, according to a database by the Gerontology Research Group.
