The year Alexander Imich was born, Theodore Roosevelt was president and the Wright brothers piloted their first powered airplane.
Imich, born in 1903, is the oldest man alive, at age 111.
Imich took the title of oldest male supercentenarian - someone over 110 - when Arturo Licata of Italy died on April 24, just shy of his 112th birthday.
However, Imich is not the oldest person in the world. Sixty-six women are older than him, with the oldest being 116-year-old Misao Okawa of Japan, according to the Gerontology Research Group.
His secrets to longevity? Imich cites the fact that he and his wife never had children, reports The New York Times.
Imich also said he was always athletic and gave up smoking long ago, reports the Times.
Additionally, he doesn't have a big appetite and eats "like a little bird," one of Imich's friends told WABC-TV in New York City.
Imich, a Polish immigrant who lives in New York City, is a scholar of the occult and published a book on paranormal activity at age 92, the Times reports.
Even at age 111, Imich doesn't have all of life's answers. He told WABC there's one thing he's still trying figure out: "I wanted to understand the universe and myself in it."
