People ask me if I ever thought of writing a children's book. I say, 'If I had a serious brain injury I might well write a children's book', but otherwise the idea of being conscious of who you're directing the story to is anathema to me, because, in my view, fiction is freedom and any restraints on that are intolerable.
Everything seems fine until you're about 40. Then something is definitely beginning to go wrong. And you look in the mirror with your old habit of thinking, 'While I accept that everyone grows old and dies, it's a funny thing, but I'm an exception to that rule.'
