the weight of the world rests upon my chest

I have this enormous pain just to the right of the center of my chest. I woke up with it yesterday morning. It feels like I pulled some kind of sternal muscle. Shelly B think I may have broken a rib and should go to a doctor immediately. Instead, I've spent the day holed up in the RV doing these endless analyses for this pair of talks that I'm giving tomorrow. If I have pulled a muscle or broken a rib, I did it while I was sleeping. I've had a cough, and I've heard of people messing themselves up while in the midst of a phlegm-hacking-fit. Anyway, enough complaining.
