Am I right using this as a proof that fat doesn't mean warm? 1: Baby are able to survive in the cold due to fat, so I'll never die in cold.           Babies have brown fat that actually generates heat when burned, unlike white fat ( hamplanet fat) which is an insulator it doesn't produce the heat.  2: I never get cold due to the fat.            Well it is an insulator, but eventually you run out of the heat because there is no source (muscle) to replenish the heat. 3: People with no fat and muscle always cold.             Fit people with small amount of fat or lacking it will loose heat faster true, but they can reheat themselves faster with muscle activity unlike fat people.  This somehow reminds me of the saying, give a man a fish he will eat for a day, teach a man how to fish he will never starve. The hamplanets will have heat initially but wont produce after it is gone, build muscle and the heat production never ends. Can this be a good argument?
