Q. If you could travel in time, where would you go and why?

My wife, who introduced me to Doctor Who, found this exchange in an interview with the actress who plays the companion on the new BBC series. Bear in mind, this actress has just completed filming a season of episodes about a guy who can travel in space and time. It’s not like this kind of question was completely out of the blue.

Talk about self-centered!
