Unfortunately, what most kids want to be when the grow up is propaganda fuelled dreams. Doctor, astronaut and police man are only attractive because of the "hero" complex we instil ... shove into kids' brains from the TV and schooling.
I wanted to stop bad guys... now, I just write speeding tickets. (and clean up dead bodies from car accidents, and bust destroy people's lives over a plant.) If kids were actually told what police really do...
If I could go back in time, I would smack some teachers very very hard.
