One of the most happy-tear inducing moments of the Olympic torch relay was when 13-year-old torch bearer Kieran Maxwell, who lost his leg to cancer and now walks unsteadily with a heavy prosthetic limb, stumbled and fell. Immediately, his family and neighbors hurried to his side to help him. And, as he has with every other setback life has thrown at him, Kieran stood right back up and kept going, with a smile on his face. All across the world, hearts swelled.

Particularly moved were Colin and Chris Weir, Britain's largest lottery winners, who have donated some of their millions to buy Kieran a lighter, state-of-the-art prosthetic limb. Kieran's family had been fundraising to buy him the new leg, as his current heavy prosthetic restricted his movement; his mother told the BBC, "He couldn't believe it. I am still pinching myself...He can go back to being a normal boy. He can be himself. Words cannot describe what they have done."

The Weirs have donated to other causes since winning their jackpot, saying they wanted to "share the luck." And in doing so, they are transforming lives. How's that for a torch to pass on?
