Two things here.
1. I, too, have a HUGE fear of Aortic Dissection and I wish there was a way to know I could prevent it. I am constantly checking to see if I have symptoms of the various connective tissue disorders.
2. I know that if my aorta was actually dissecting, I likely wouldn't be typing here. However, for me, it's not always the fear that it is happening right this second, but that it is about to happen. I feel like my body is constantly warning me that I'm about to die. So, Dragi, I definitely understand what you are saying, but for me at least there is another layer of fear that is going on there.
