"The zombies are unlikely to eat your brain, because you'll be too busy using it against them. You're not 100% prepared for a zombie attack, but you're smart enough to improvise under pressure. Since you know that one reckless mistake could end it all, you'll be extremely careful about every move you make. You'll defend yourself with whatever you have available, and your creative solutions might just keep you alive. Humankind is lucky to have you on our side."
How encouraging! Now to finish customising those monster trucks and to have the final fitting for my lightweight body armour!
