I must say that I feel better prepared for the inevitable zombie onslaught after having read this.
It's lucky for me that I live on the 3rd floor - I have not one but two sets of stairs to destroy should my exterior defenses be breached.
I would have given this manual 5 stars but for one thing: Several times, the author refers to zombies who have "traveled the ocean floor," etc. While it may be true that zombies don't need to breathe to continue existing, I am quite sure that the immense pressure at the bottom of the ocean would be enough to crush a zombie's skull, thereby destroying the brain and ruling out the possibility of it resurfacing to infect and/or eat humans.
I may write to Mr. Brooks to make him aware of this.
