The Daily Mail reports a story proving that old age and treachery really can overcome youth and inexperience.

A 70-year-old former British soldier who fought guerillas in Aden and Triad gangs in Hong Kong showed four muggers how it doesn’t pay to mess with the SAS.

Douglas O’Dell is past retirement age but the moves he learned as a volunteer in Britain’s toughest regiment half-a-century ago stood him in good stead when he was ambushed near his home in Bielefeld, Germany, by four local toughs.

The former Provost Sergeant put paid to the danger on the street like he once took out bandits in hotspots across the globe.

THWACK! The first mistake came when one of the teenagers grabbed him around the throat and said in German: “Give my your money, grandad, if you don’t want to get hurt.”

“Bad move,” said Douglas. “The only part he got right was grandad. If you’re gonna grab someone from behind take their arms and pin them to their waist.

“This joker, I was able to grab his elbow, crouch down and throw him over my shoulder. He landed on his back on a fence and squealed like a stuck pig.”

CRASH! As one went down another moved in and Douglas thought he saw him reaching for a knife. The Birmingham-born divorcee, who has a daughter and three grandchildren, said: “I had the measure of him but I slipped on some wet leaves as he came for me and bashed my face badly on the concrete.

“I saw his boot coming towards my face and I thought: ‘No you don’t, sunshine.’ I grabbed his leg and twisted it until he too was screaming out in agony.

“Then I got to my feet and kicked him in the chest.”

With two down the two remaining would-be muggers had enough. One peeled his groaning pal from the fence, the other picked up his crippled accomplice from the pavement.

“The last I saw of them they were limping down the pavement like a WW1 trench raiding party who got clobbered,” said Douglas.
