Ninety-nine-year-old war veteran Tom Moore has raised more than £12 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.
So far, more than 600,000 have given.
Within half a day Tom – a former captain who fought in India and Burma – hit the £3 million mark.
He’s now soared past £12 million – and the donations keep coming in.
Mr Moore said: “Completely out of this world!
“Thank you so much to all you people who subscribe to the National Health Service because, for every penny that we get, they deserve every one of it.
“I think that’s absolutely enormous.
“At no time when we started off with this exercise did we anticipate we’d get anything near that sort of money.
“It just shows that people have such high regard for matters of our National Health Service and it’s really amazing that people have paid so much money.”
Tom was looking to walk 100 lengths of his Bedfordshire garden before he turns 100 on April 30th.
