Fortunately true. We just have to be very careful about answering questions like this - our first concern is to try to ensure that no one ever reads this thread and goes, 'Hmm, yeah, hypothetically one would probably kill the other, but maybe not - I wonder if I could try it myself.' I'm guessing that Nancy's first response was partly to make sure that this was only a hypothetical situation in this instance, and partly to make sure that no one reading the thread later could possibly get the idea that trying it out might be OK.
