Thanks for that, Pat.  It was an excellent picture.  I had two friends who died 
of a ruptured aorta; now I know what happened.  I always imagined it would have 
ruptured directly next to the heart.  The abdominal aorta is also bigger than I 
imagined.

  Have you heard of abdominal aortic aneurysm?  Here's a diagram showing the 
aorta in the belly button area.
