Jason, I found your question on the possible connection between mercury and aneurysms very interesting because lately I have been wondering about the same thing. My mother died of a brain aneurysm three years ago. She had high blood pressure but was otherwise fairly healthy. Although as I look back now with the knowledge I have now, I can see indications that she was suffering from mercury poisoning to some degree. She had a mouth full of amalgams, and had had them all her adult life. Of course, some of that was passed on the her babies (me and my siblings) as well.
Anyway, if you hear any more on this topic I'd love to hear it too.
