I can't believe I make more than Astronaughts and they're out there risking their lives in outer space.
To be more precise, I was really trying to thing of an example where it's dangerous to not be precise, for example if an astronaut makes a mistake his space ship blows up, so in that profession, truly one needs to be a perfectionist as opposed to delivery guys.
Maybe a better example would be cosmetic or brain surgeons or something.
