Recently, I was reading about some "miracle survival" stories (where a person "beat the odds" or was a sole survivor in an event.) I stumbled across some information about the aorta, which is the main artery of the body. It transports blood from the heart to other arteries that supply the organs of the body. I know that the heart cannot handle sudden deceleration or the power of G-force. What I didn't know is that the tissue that connects the aorta to the heart is apparently fragile. When I read that, I thought "Wot!......Woot!" (as the young people say) and the brain sent a message to the eyes: "Whoa! Back up and read that again, will ya?" I was really surprised at this fact and just assumed that the aorta would be attached to the heart, with some "industrial strength" tissue. It's the most important artery in the body. I will try to find the link I was reading - forgot to bookmark it. Edit: Note to self to remind me that I have to come back to this thread and also I have to finish a section on the skin thread. I'm working on the program summaries of 2 assemblies first.
