“He” will not be able to alone .There will b groups that band together as in The Walking Dead.
Not going very far... newer cars wont start and there is no power... no electricity for anything. Literally going back to 1800, but without the knowledge or skills to live in 1800. 80% kill off in one year nation wide. Without the necessary ability to curb mosquitoes... 90% kill off in the deep south when adding malaria and other skeeter borne disease to the mix. Marauders, pirates, cults, cannibals, rouge military units and every other type of bad actor you can think of roaming around. It’s all good though because I know, as does my family, who their Lord and Savior is. Our last exhale here will result in our first breath in the Glory of Heaven. Won’t suffer anymore than Jesus did I guess. Probably just last a little longer... Have a nice day!!!
