In life I've found worrying is a total waste. As far as I know I don't have a life threatening disease, but that doesn't mean that I will wake up tomorrow. If you are worried get the test.My college room mate was one of the best men I've ever met. He was in perfect health and had everything.... wealth, a beautiful girl, and was a constant over achiever.... until he dropped dead suddenly of a pulmonary embolism. He always admired me and wanted to emulate me, I never got to tell him how much I admired him. He was 27.
