      The Notre-Dame cathedral is burning down right this minute. It is sad to watch an 850 year old monument go up in smoke. Apparently the big wooden steeple which was 70 meters high was constructed with lots of lead elements so as soon as the structure caught minor heat it all went like domino. I’ve been to Paris twice and never had a chance to see the cathedral, stupid me.

      The news about that black hole thing made me think. Now forgive me, physicists and others, for being such a noob when it comes to astronomy, but I had this idea, which didn't sound too stupid to me, but again, I'm a real layman in astronomy.
      I was thinking that the big bang may have been a black hole, being overloaded with everything else the universe held, such that it became unstable, and exploded? Additionally, if I'm right, black holes grow while eating stuff, and may eat each other. What if our whole universe will come to a point in time where there are only two black holes, which have eaten anything else, remaining only for one to eat the other one, leaving only one giant black hole, once again being overloaded, and exploding, like a new big bang?

      In the hospital environment, a lot of letters must be written. I'm looking for a way to standardize all letters I'm making. To do so, I would like to make a MS Office Word wizard, which just asks me all relevant things (e.g., salutation, patient name and birth date), lets me select all things in clinical examination that are deviant from a list ..., and then merges everything into a standardized document, which would be a bit easier than making a template.
      Does anyone know how I can do this?
