Simon Wiesenthal, a survivor of the Nazi death camps, dedicated his life to documenting the crimes of the Holocaust and to hunting down the perpetrators still at large. 'When history looks back,' Wiesenthal explained, 'I want people to know the Nazis weren’t able to kill millions of people and get away with it.'

Randy Pausch, featured in This Way Up a few months ago, died on 25 July 2008, aged 48. 

A computer science professor, he achieved accidental fame with his 'last lecture', delivered to colleagues and students after being diagnosed with terminal pancreatic cancer. A video of this remarkable, optimistic performance - originally shot for his three young children - ended up posted on the internet. It inspired millions to appreciate the briefness and preciousness of life.

Jazz legend Sonny Rollins says he is still searching for his ultimate performance.

by Geraldine Royds

Born in the rough New York neighbourhood of Harlem in 1930, Rollins believes that, despite the racism and hardship, he was lucky to be born at a time when there was so much music around.

He started playing saxophone when he was a child and by twenty years old was playing with the likes of Charlie Parker, Miles Davis and Thelonious Monk.  Rollins idolized Parker and followed him into the abyss of drug abuse. Although Parker couldn’t pull himself out of it, he managed to inspire the younger Rollins to get clean.

The bad news is physical decline is inevitable. The good news is that creatively and spiritually we can continue to flourish until the end of our lives. From artists to ballet dancers and Wall of Death bike riders, be inspired by the amazing old people collected here. It's a small selection - there are many more out there!

Louise Bourgeois is one of the world’s greatest contemporary sculptors. Her themes are femininity, sexuality and isolation. Aged 88 she became the first artist to fill London’s Tate Modern's Turbine Hall. She reached the pinnacle of her career eight years later when the Tate Modern held a major retrospective of her work. To this day she continues to defy convention.

It’s the stuff of heroic legend. A rich man goes walking in the Himalayas seeking answers to Life’s big questions.  On a remote mountain path he meets a wise man and is enlightened to his true calling.

In this instance (which more or less followed the script) the rich man is an American executive, John Wood, and the wise man the headmaster of a Nepalese school. Ten years have passed since that fateful meeting. Now Wood says, 'Even if money can’t buy happiness - lack of money can.'

Kids get a lot of bad press. We're told that they’re rude, selfish, consumeristic, with no manners, no motivation and no interest in anyone but themselves. But in fact there are engaged and altruistic young people out there everywhere.

These particular children are especially inspiring. They are not waiting for adults to do it - they are busy making things happen themselves. They are bringing about the changes they want to see.
