Damn. Not sure who else here besides me has had their sternum sawed in half... two times and counting; ( oh there's another coming) but I can somewhat speak with authority on this. Hear me out. I was born with what's called a congenital heart defect - specifically, mine is called Pentalogy of Fallot. I had open heart surgery at age 5, then again 2 years ago at age... well uh - yeah. Of course back when I was 5, I had alot of drugs and love from my family. But 2 years ago....knowing the recovery time (6 weeks minimum), for the life of me, I can't IMAGINE getting into a race car with dual shoulder harnesses. Holy Sith! My Dr. said I could drive a street car once I was able to hold the sterring wheel and look over my shoulder as if changing lanes... and that took a long, long time. You have no idea how much you use your chest muscles every minute of every day.... until you've been through something like this. To drive a race car after this like GA did... is the stuff superheros are made of. I I hist you not. I kind of wish Greg would embrace this and talk about it more. Congenital Heart Disease affects people around the globe; and it should be talked about and awareness raised. Most notable, Snowboarder Shaun White and NFL Bronco's Coach John Fox also have survived this disease, among others.
