Well, to be honest it sounds more than really fictional. I am curious whether the author believe in his own article... Though it was pretty interesting, also I am pretty sure that in the near future medicine will be at a way higher level so there will be huge potential to create the viruses that will be able to zombify the people. Sometimes I am a little bit scared that the situation of The Walking Dead will happen and the humans will be destroyed because of some dumb doctors decisions to experiment...
