The world's oldest man says the secret of long life is a good beer every day.

German Hermann Doernemann, aged 111, took the title after the death of American Fred Hale.

The retired electrical engineer says a daily dose of a good dark beer kept him feeling on top of the world.

Mr Doernemann, who lives with his children, is officially the world's oldest man but he's a long way off being the oldest person.

The Los Angeles-based Gerontology Research Group, which keeps records of the world's oldest people, says that 26 women in the rest of the world are older than him.
