People Around

Whenever i get to read some article about woz (Steve Wozniak) i get this question. Is it possible for a human being to walk away from fame and money for a different cause?. This little guy has always amazed me with the kind of experiments that he has done with life.
Amidst people who claim that they bother about the general health of the whole world?, sacrifice for an altruistic cause and things like that, guys like Woz stand out.
