I put all my faith in the next generation

why not a historian?

You put your faith in the next generation because you've seen a picture of one child in a shirt that her parents most likely picked out for her?

Why not both? You can be princess bubblegum! Never give up on one aspect of yourself to fit the aspects of another thing. Go ahead, be a girly scientist.
