7. Your Doctor is youthful and childlike5/5: Eleven4/5: Five3/5: Two2/5: Ten1/5: Eight The Doctor's ancient and he walks in eternity, but that doesn't mean that fish swimming in air can't turn him into a awe-stricken eleven-year-old every now and then. Would you be a childish, cheeky Doctor or would you be more of the serious kind? Perhaps you're the type who only becomes an old man upon wearing your glasses, like Peter Davison's Fifth Doctor, or maybe you can just ramble on like a teenager, as Ten did so often. Maybe you see the Fourth Doctor as more childlike than the Eighth; I don't know, I just think Paul McGann has that exuberant look about him.
