Matt Damon turned 45 on October 8. The actor, writer, producer and screenwriter won an Academy Award--with Ben Affleck -- for the screenplay, Good Will Hunting when he was just 27. But Damon has managed to stay incredibly grounded. On the British television show, the Graham Norton Show, he reflected about winning an Oscar when he was so young, "... I suddenly had this kinda thing wash over me where I thought, imagine chasing that and not getting it. And getting it finally in your eighties or your nineties with all of life behind you and realizing what an unbelievable waste... It can't fill you up. If that's a hole that you have, that won't fill it. I felt so blessed to have that awareness at 27."
