Ninety-nine-year-old war veteran Tom Moore has raised more than £10 million for the NHS.
Tom originally set out to raise £1000 by walking 100 lengths of his garden.
But after an appearance on network television, people started donating at the rate of one every 20 seconds.
Within half a day Tom – a former captain who fought in India and Burma – hit the £3 million mark.
He’s now soared past £10 million – and the donations keep coming in.
His Twitter account said: “We cannot wait to tell the news to Tom in the morning, he will not believe his ears!
“Thanks each and every one of you – we are in awe of you, but especially our frontline staff who need this now more than ever.”
Tom was looking to walk 100 lengths of his Bedfordshire garden before he turns 100 on April 30.
He told BBC News: “It seems almost like fairy land to think that we started off at 1,000 to a sum of money that’s not believable, is it?”
“I never imagined anything like this, but I’m so pleased, and I hope it just goes on because the services I got from all these doctors and nurses was absolutely outstanding.
“And they’re such nice people too.”
