A 107-year-old from Luton could be the oldest Great War veteran in England.
The UK's World War I veterans association has just 33 members
Albert Dye lives in the Edwardian Care Home in Biscot Road, Luton.
He could now be the country's oldest veteran following the death last month of 108-year-old Jack Davis, of Stoke Hammond in Buckinghamshire.
Mr Dye, who has lived in three centuries, keeps in good shape with a daily work out that includes marching on the spot, arm stretches and deep breathing.
In 1915 he was sent to Egypt to fight with the Army Service Corps and the Royal Field Artillery.
A spokeswoman for the Veterans Agency, an arm of the Ministry of Defence, told BBC News Online it would be difficult to verify who is the oldest veteran from the war, or even how many survive.
She said: "As there are so many veterans out there, we only keep records on war pensioners."
After the war, Mr Dye worked as an engineer.
His wife Emily died in June this year, aged 90.
