With roughly 72,000 centenarians in the United States, it's not all that unusual to find several clustered in the same city.
But to have several living under the same roof in the same city?
That's rare, says Thomas Perls, director of the New England Centenarian Study at Boston University.
A wealthy retirement community in Providence, , boasts six centenarians. The oldest, Elsa Zopfi, is 104 years old. The youngest, David Richardson, celebrated his 100th birthday on Sunday.
Robert Kenyon, who is 102 years old, says he doesn't think about his age all that much, he just tries to take one day at a time.
Samuel Bender, who is 100 years old, says he thinks about all the adventures he had. He says life has been an achievement.
