GREAT FALLS, MT - JULY 23: Walter Breuning, at age 112 now considered the oldest man in the world, waits for an elevator on the way to his room at the Rainbow Assisted Living Facility on July 23, 2009 in Great Falls, Montana. Bruening, born Sept. 21, 1896 in Melrose Minnesota, inherited the title when Henry Allingham of England died last weekend. Breuning moved to Great Falls in 1918 with the expansion of the railroad and worked in the railroad business for 50 years. He says he stays healthy by eating just two meals per day and excercises by strolling the halls of the retirement home with the aid of a walker. He shuns medicine, except for one low-dose aspirin per day. His earliest memory is of hearing his grandfather talk about fighting as a Union soldier in the Civil War. Bruening has no living relatives. The Guinness World Records is expected to make the official announcement soon, after verifying his records. (Photo by John Moore/Getty Images)
