I see that the video link that I put in my block was something National Geographic held the rights to. I was not aware of this because it was in a tweet and was a Youtube video, which are mostly free access. As an author, I would be the first to say things should only be used with permission (despite the fact that a number of my articles appear on the web without permission). My apologies. And all the proceeds of A Matter of Tea will still go to the victims of the quake and tsunami.
