Scheint so, oder vielmehr nach “Rückengefühl”, denn in seinem neuen Buch (siehe rechts) schreibt sein Sohn:

My father will sit down and give you theories to explain why he does this or that. But I remember seeing it as a kid and thinking, Jesus Christ, at least half of this is bullshit. I mean, you know the reason he changes his position on the market or whatever is because his back starts killing him. It has nothing to do with reason. He literally goes into a spasm, and it’s this early warning sign.

If you’re around him a long time, you realize that to a large extent he is driven by temperament. But he is always trying to rationalize what are basically his emotions. And he is living in a constant state of not exactly denial, but rationalization of his emotional state. And it’s very funny.
