That's the gist of the government's new guidelines for what to do if a terrorist detonates a nuclear weapon in the city. If you freak out and run around in the streets screaming like a banshee, smashing windows, and biting people just because finally you can, you'll probably die from the nuclear fallout. If you just stay in your apartment — ideally, in the basement — and hang out for a while, maybe play a little Scrabble, you'll have a much better chance of survival. [NYT]
