Every day I go to my study and sit at my desk and put the computer on. At that moment, I have to open the door. It's a big, heavy door. You have to go into the Other Room. Metaphorically, of course. And you have to come back to this side of the room. And you have to shut the door. So it's literally physical strength to open and shut the door. So if I lose that strength, I cannot write a novel any more. I can write some short stories, but not a novel.
