Four years ago, Dan Black was paralysed in a cycling accident.
Ever since, he has been raising money for pioneering stem cell treatment which could one day help him walk again.
But now, after collecting £20,000, the 25-year-old has given it all away – so a little boy can learn to walk instead.
Mr Black abandoned his own dream after hearing about five-year-old Brecon Vaughan, who lives near him just outside Chepstow, in South Wales.
Mr Black, who is wheelchair-bound, said he made the extraordinary gesture because Brecon had a better chance of walking than he does.
‘I know for me that things aren’t going to get better any time soon,’ he said. ‘I just wanted to do something that could help someone whose life could get better.
‘Brecon can definitely walk if he has the surgery. I wouldn’t wish being paralysed on anyone, so if I can help someone walk, I will.’
