How useful are you?

I always carry matches with me, just in case, for some unknown reason the universe shoots me back in time. Who knows why it would happen, I just always thought that matches would be handy.

This quiz shows that on a technological level, I'd be almost useless. But still, I think common knowledge of a lot of things would do just as much, if not more, than technical knowledge.
