Nothing wrong with fantasizing on the maniac level either so long as someone does something about it, yeah. I can't imagine living a caged life like that myself, its a really depressing thought that some people even feel like they have to.
I think I would like to be an investigator of some sort. I really do already do pretty much what I want to. So, if you find that out, there's the answer waiting.
Investigative journalism would be interesting I think, or being a journalist that gets to travel the world going to dangerous places. I would love to do that.
