Yes, agree about iodine. I'm starting to come down with the thing that's been going around campus, but since school's been in session for 2 months, that's a huge improvement from the past when I would have been one of the first people smote down.
Re chemtrails - I believe anything that's not discussed in public is a conspiracy. That's the definition of the word. Nobody in power will explain what they are so, ergo... If they were benign, there wouldn't be a reason not to explain.
