Walter Breuning, the world’s oldest man and second-oldest person, has died in the US, aged 114. Breuning died of natural causes in a Montana hospital, said a spokeswoman for the retirement home where he lived.He was 26 days younger than Besse Cooper of Georgia, whom the Gerontology Research Group in Los Angeles lists as the world’s oldest person at 114. In an interview with The Associated Press last autumn, Breuning attributed his longevity to eating just two meals a day, working as long as he could and always embracing change – especially death.‘‘We’re all going to die. Some people are scared of dying. Never be afraid to die. Because you’re born to die,’’ he said. Breuning was born on September 21, 1896, in Minnesota and spent his early years in South Dakota. That first decade of the 1900s was literally a dark age for his family. They had no electricity or running water. A bath for young Walter would require his mother to fetch water from the well outside and heat it on the coal-burning stove.
