Wow, Choate biophysics now. Do the thermal conductivity/inertia calcs. -40F *air* can't drop your coretemp in 30 seconds. Do the math. Or go up to the Dakotas this winter and step outside for half a minute. It hurts but doesn't kill that quickly. When the cabin is breached you don't have time to gather air to hold your breath. ---- Homeland Security Status: Yellowbelly
