I found this picture of my dog recently and it made me think. If my dog was wandering around a bunch of zombies, would they eat him or think of him as a zombie. Then that led me to think. How do zombies recognize other zombies. The film Shaun of the Dead made a pass that all you had to do to fool a zombie was to walk slowly and moan. Resident Evil on the other hand works on the assumption that it's all a virus and the virus knows what other things have the virus in it. Do they just smell the living blood coursing through our vains? Obviously not all zombies have eyes so there's got to be something that attracts zombies to people. If that is so, and it is some kind of scent or noise or visual cue, could there be a possibility of producing something that could make us virtually invisible to zombies? Could there be something that makes a zombie think that we are a zombie and pass us right by?
