World's oldest living person Grigoriy Nestor, who had witnessed both the World Wars, has died at the age of 116 in western Ukraine.
Nestor, who died Sunday, was born March 15, 1891 in a village in Lvov region.
The man had reportedly never felt ill or taken any medicine throughout his live. He had also never drunk heavily.
Nestor, who worked as a shepherd, used to say that he was able to live so long because he had never been married and had not had his nervous system "undermined on the marital front".
According to the Guinness Book of World Records, the world's oldest living person today is 115-year-old Emiliano Mercado del Toro of Puerto Rico, who became the oldest woman after Elizabeth Bolden, an African American woman, died at the age of 116 years and 118 days in 2006.
