Meet Walter Breuning, he celebrated his 114th birthday on September 21, 2010 and that makes him the oldest known man in the world. He's a retired railroader, a widower for 53 years and for the last 30 years he's been living at a retirement home in Great Falls, Montana. His mind is sharp. He still walks to the dining room for his meals. He takes no prescription medication. He only stopped smoking in 1999, at the age of 103.
