A 112-year-old Montana man has become the world's oldest living man after 113-year-old Henry Allingham of England died Saturday.

Walter Breuning was born Sept. 21, 1896. He learned to read by kerosene lantern, remembers his grandfather telling him about fighting in the Civil War, and cast his first presidential ballot for Woodrow Wilson.

Now a resident of the Rainbow Retirement Home in Great Falls, Breuning takes one aspirin and eats two meals a day. He strolls the halls daily wearing a suit and tie, and still walks the ramps to his second-floor apartment.

Breuning's longevity advice? Stay active in body and mind, don't eat too much and be good to people.
