Agreed. At 46, and having been a night-owl pretty much my entire life, I'm skeptical that you can just "switch" to another mode. Maybe you can, through very conscious and focused effort, manage to adapt to what appears to be a "morning person" lifestyle; but I suspect that people who do that are ultimately just faking it.
That said, I've never looked at being a night-owl as something that needed to be "fixed" or something that I'd want to change.
