Space Nerds are, you guessed it, space nerds!
These sims are obsessed with the stars above and whatever may be lurking in them. They are fascinated by alien life and want to explore any other worlds they can find. They have a natural talent for all mental skills, but especially rocket science. Sometimes they may become Fascinated by Space, which means they ignore everything else but their love for space! They are true space fanboys/girls.
This trait works best with Get to Work installed because that EP includes aliens and Sixam
It will also work hand in hand with the UFO Investigator trait by r3m (totally subtle recommendation, honest)
