I bought the soundtrack for "Pirates of the Caribbean" a few days ago, and now I'm scribbling down things for my own sequal. Of course I would star in it. ;-)
I think I know why I was so tired and run-down by the end of yesterday... forgot to take my vitamens that morning. One chewable multi-vitamen, Omega-3 fatty acid (since I don't eat fish), B12 (since I have a tendency for single-digit blood counts), and Vitamen C (to boost my much-abused immune system). It seems to work, I stay mostly healthy.
