The utmost generosity...

...that's being an 'altruistic organ donor' - someone who volunteers to donate an organ while still alive. There is a charity called 'Give a Kidney - One's Enough', dedicated to raising awareness of altruistic donation, those people who simply decide to help others they'll probably never know, by donating an organ they don't need. But how many of us would ever dream of doing it? And what are the dangers?

Well, all of those worries did not deter a man I met today. At 83, he decided two kidneys was one too many for him in his remaining years, and he sought out how to donate one of them.

He's now the UK's oldest living donor. He's the lovely Nicholas Crace, from Overton, whose mind was totally made up after he was told he had 'Formula One' kidneys that could easily belong to someone 40 years younger!
