It is stated at one point by some CIA guy that North Korea was able to avoid the zombie outbreak by systematically removing the teeth of all of its residence in less than 24 hours. The reasoning being that if nobody had teeth then the virus couldn’t spread because nobody could bite anyone. He states that it was “the greatest feat of social engineering ever achieved”. Like I get this is a fictitious plot but they can’t even avoid making up the most utterly deranged bullshit lmao.
