Personally I think when your peers are worried what they are doing Saturday night and you're worried about the world economy collapsing, and global warming, and quarks and quasars... it's natural you'd be a little more anxious wink.

I hate to say this (sorry guys) I think it also has allot to do with how more gifted children are raised, in cases where the parents don't properly acknowledged their children's gifts/special needs (again, personal experience on this one).
