I've been thinking a lot about the zombie apocalypse idea, and what it would take to survive. (The slow "Brains" kind of zombie. If we get the "28 Weeks Later" kind, we're f-ed.)
Obviously, the big issue is not getting infected, so blades are a sucky idea. And they will keep on coming until they physically cannot move anymore. So we need martial arts. Sophisticated martial arts.
The most sophisticated martial art on the planet, I'm told, is Tai Chi. It's practiced very slowly, so no one who practices it actually knows how to fight anything other than a sports replay. That's okay for us, because zombies are slow!
