Zombies are apocalyptic in nature. They belong to a class of monster that doesn't just hunt humans, but seeks to obliterate that entire human race.

The dead walk among us.

When I started writing, there was nothing about zombies. It was all teen movies, which to me are scarier than zombies, but that's another story.

But there were alternative media outlets. Oh sure, and you know who listens to them? Pansy, overeducated know-it-alls, and you know who listens to them? Nobody! Who's going to care about some PBS-NPR fringe minority that's out of touch with the mainstream? The more those elitist eggheads shouted "The Dead Are Walking," the more most real Americans tuned them out.

You can watch 'Dawn of the Dead' and still sleep at night. Try that with 'The Day After'.

I think 'G.I. Joe' is a perfect example of how I'm the world's worst businessman. If I were smart, I'd be writing 'World War Z Part 12', but I have to go where the muse leads, and I've always been a huge 'G.I. Joe' fan. I always wanted to know more about these characters, these little plastic figures I played with as a kid.

Any survival guide will tell you, don't buy a pair of combat boots before any disaster. They'll tear your feet up. Or water. Don't bring water with you because it'll tire you out and you'll lose too much fluid. Bring a water pump.
