Perhaps the root explanation of why he writes about himself so much is that he is a passionate observationist/scientist. He observes a lot of the things around him, measures these things, things about their underlying models, and writes about what he discovers. This is what he loves to do. His body is always at hand as a possible observational subject, and he is more than willing to volunteer himself as a guinea pig. Hence, he does end up writing about himself more than most people. But he writes about everything more than most people. He is not just verbose about himself, he is verbose about everything. I for one can chuckle at that quirk. I find many of his publications brilliant and enlightening, and his process and work ethic very inspirational.
