Stunning news today in the journalism world... Anchorman and Meet the Press host Tim Russert collapsed today in NBC's Washington news bureau of an apparent heart attack and later died. This grabbed my attention, aside from the obvious reason, because he had just returned yesterday from a trip to Italy. My wife and I have seen an episode of Dr. G: Medical Examiner where a man of similar age died suddenly after a transatlantic flight. The mystery diagnosis turned out to be a pulmonary embolism, a condition aggravated by long periods of being sedentary...such as on a long flight in a cramped seat with little movement. Deep vein thromboses in the legs break free and travel to the heart, usually causing death. I would be surprised if this were not discovered to be the cause of today's sad event.
