The day after Armageddon, humans will be perfect, so they'll instantly have knowledge of wilderness survival. Also, reading the Awake magazine for six months is equivalent to a college education, so most of the JWs will be the equivalent of PhDs (this ignores that most JWs don't actually read the magazines). And if reading the mags makes you college-smart, think of how smart the writers of the magazines are. They must be like walking supercomputers.
