"The zombies are coming!" the US Homeland Security Department warned yesterday.
Government posters urged citizens to prepare for a zombie apocalypse, part of a public health campaign to encourage better preparation for genuine disasters.
The theory runs: if you're prepared for a zombie attack, the same preparations will help you during a hurricane, pandemic, earthquake or terrorist attack.
Among the government's recommendations were having an emergency evacuation plan plus keeping on hand fresh water, extra medication and a change of underwear.
