Medieval peasants survived brutal winters reaching -40°F without modern technology through an interconnected system of nine survival secrets: perpetual pantries using drying, salting, and fermentation; communal sleeping with livestock for body heat; hot stone radiators storing thermal energy for 8 hours; ash banking to keep fires alive for days; multi-layered wool and linen clothing engineered for extreme cold; snow banking walls for natural insulation; high-fat diets generating internal heat; multipurpose tallow for waterproofing and fuel; and maintaining protective skin oils. These weren't primitive methods but sophisticated thermal engineering proven effective for centuries, offering modern lessons in resilience when our fragile systems fail.
