Some doorknob has dropped some ricin in Vegas. There is no antidote to ricin. If it gets in your system, you shall die. As little as 500 micrograms, or about the size of the head of a pin, can kill a human. I read that this is not considered a terrorist event. We shall see.

Come to think of it, there is no antidote to life either. If it gets in your system, you shall die. Oh well . . . .
