I was talking to my little brother and he asked me something that is stuck in my head. Ok it plays out like this:
You are walking down the middle of the road with a chainsaw (for all the nay sayers out there go with it for now) when a small group of zombies comes breaking out of the house. You start up the saw and kill all of the zombies but one which is behind you when you turn around the zombie bites you on the hand.
Now if you take the saw and chop off you whole arm will you still turn? or will you be ok becuase you didnt allow the virus to spread.
