Rocket Scientists

I've always wondered what it would be like to be a rocket scientist. So many people use the phrase "It doesn't take a rocket scientist..." that I'm curious how rocket scientists actually feel. Do they feel left out, as if their supreme knowledge on jet propulsion doesn't matter when doing simple tasks, or do they feel good to know that there are some things that do take a rocket scientist to figure out, and that unlike the rest of us, they know how to solve those problems. I often wonder where the phrase comes from as well. Obviously, rocket scientists seem to be more "intelligent" than the average human, but being a rocket scientist can't be the hardest job in the world. I think it would be harder to clone an animal than design a nuclear warhead. For that matter, I think it's harder to figure out the opposite sex than it is to figure out space shuttle trajectories. So maybe those rocket scientists aren't so smart after all...
