I read about the Donner Party and learned most the young, lean and muscular adults died first, and the overweight, middle aged people survived as a much higher percentage of the survivors. Their added fat stores allowed them to survive longer…until they pushed through on those that passed away of starvation early on (no body fat) and preserved in the frozen environment until help arrived.
AFTER reading their account, I soon developed the Donner Party diet strategy and gained 50 lbs. Bring on the apocalypse - I’m ready with my personal food storage! (seriously, I’m kidding, but I have stocked up on seasoning just in case).
