Alexander Imich claims that he has never drunk, always eaten healthily and was a keen gymnast and swimmer when younger.
And now, at 111 years of age, he is officially the oldest man in the world.
Known as a supercentenarian – which is someone who is older than 110 – this New Yorker gained the title when Italian Arturo Licata died on April 24, a week before he was due to turn 112.
Originally from Poland, Alexander was born on February 4 in 1903 and emigrated to the US with wife Wela in 1951. The retired chemistry professor has lived in Manhattan since 1986, when his wife passed away.
As for the world's oldest woman, 116-year-old Misao Okawa from Japan currently holds the crown.
