Ask Dr. Paul

It's time for everyone's favorite feature: Ask Dr. Paul. This time our question comes from Laurie on Twitter.

Laurie: The History Channel is talking about the end of the world. Is that history already?

Dr. Paul: Yes. Yes, it is.

If you have a question for Dr. Paul, send it, comment it, or write it on a piece of paper and stick it in a jar in the middle of a field with a rock on top in case some wolves passing by bump into it they won't knock it over and make the paper blow away.
