Ask your grampa. Good idea. Grampa, you know the Peanuts comic strip? Sure. When did they guy who use to draw it die? Oh, you mean Charles Schulz? I think he passes away in the year 2000. See? I told you it was back in the olden days.
Let's not bother gramma right now, Nelson. She's busy worrying. How come? Well, she is convinced that the things she worries about the most never happen. So she feels it's up to her to keep worrying about them to make sure they never do happen. It's a lot of responsibility. Who knows what kind of chaos would break loose if she were to stop worrying? Back in 2000 she worried the Y2K bug into oblivion. Now she's working on preventing the end of the world in 2012. Good job, gramma!
