He could well be. I have another weird theory about the Doctor. The Seventh Doctor stated that he was 953 years old at some pij t and the War Doctor says he is 800 years old during The Day Of The Doctor. I think the Doctor restarted his age when the War Doctor first came on screen as he no longer called himself the Doctor. He looked much younger in The Night Of The Doctor than in The Day of the Doctor and that could have been an 800 year gap.
