I've met him twice, so maybe not the best to say, but yes. Every time I've spoken to him he's been completely wide-eyed, bat shit hilarious. Lives in a world of his own. Still very much 'The Doctor'.
He's in rude health.
Walks with a stick, but otherwise completely with it. Looks like the type to make 100 IMO,
God, I hope I haven't tempted fate there..
