I think none of you are surprised that I'd say I would be a history teacher if given the chance. Though my plan B would certainly be a science teacher especially in the field of evolutionary biology, or astronomy. Though I don't need a class-room, and none of my pupils have to be students. I feel like I am a history and a science teacher with my Facts of the Day. I'll even let you'll chew gum and look at your cell phones.
What subject would you teach?
