This can be an interesting thing to be aware of and play with. Taking his example of pain - if you know that your reported perception of pain will be down to your own judgment and where it sits within your narrative, you can start to play with the narrative, lie to yourself, alter your response. A simple example is in physicality. Suppose you're rowing a 2km race. You break it into eight 250m chunks in your head, because a 250m sprint is am easy thing, and aa long as you knowingly don't know that there's more pain coming, you treat each sprint entirely independently, and squeeze that much more out of yourself. A slightly more complex example is in flat-out rewriting, where you consciously choose to either interpret or reinterpret an event in a light you convince yourself to be true. Years later all you remember is your new truth. I mean, people do the latter inadvertently and crappily all the time, as he describes. Why not do it deliberately? I quite like being in charge of my narrative, even if I cheat with tippex and autoindoctrination. Sure, you end up forgetting which reality is really real, but again, it doesn't really matter - narrative reality is entirely subjective anyway.
