There was enormous publicity when Malala Yousefzai won the Nobel Peace Prize last year. This rather overshadowed the fact that she shared the prize with the Indian activist Kailash Satyarthi. He's made it his life's work to campaign against the use of child labour in his country. He's risked his life to do it - but so far he estimates that he's been able to rescue about 80,000 and at 61, he shows no sign of slowing down.
