The oldest man in the world just turned 113 and he currently resides at the Rainbow Retirement Home in Great Falls, Mont.
Despite his age, he is still quite a pistol.
Walter Breuning is the oldest man in the world, but said he doesn't feel a day over 93.
"I don't see any difference between 113 and what I did 10 years ago, it's about the same," he said. "Just another birthday on top of each other."
He attributes his longevity to exercise and a healthy diet. But his friends say God has kept Walter on earth so long because he brings joy to others. The feeling appears to be mutual.
"He has yet to miss a day saying 'Hello, Jo Ann,'" friend Jo Ann Robitalle said. "He is really sharp."
"He will talk to anybody and everybody," she added. "But I just don't want him to get too tired, because people have been coming and coming, asking him a lot of stuff because he's famous. But he's famous and nice."
George Pamenter has been friends with Walter since he was 40 years old and said he continues to stand by his principles.
"He's the same self-determined individual now as he was then," Pamenter said. "He knew what was right and what was wrong, and he kept to that and he didn't care who disagreed with him."
Walter is a living example of new research indicating positive emotions are a key factor to longevity.
Over the past decade, several studies say even more than diet and exercise, the way we feel determines how long we live. Our bodies fight-off disease and decay with happiness, connection to community, and a strong spiritual life.
Walter is a poster child for all of the above.
"I look at him and I think, why can't I be like him?" asked friend Lydia Laubach. "And I went over to him and I told him to have a wonderful day today, and he says 'everyday is a great day.' He's just such an inspiration to not only me, but to other people."
Walter is independent, a deep thinker and believe it or not only takes one aspirin a day.
He was born in Minnesota, but moved to Montana in 1918, where he worked for the railroad for 50 years and is now one of the most celebrated people in the state.
