> The news comes 11 days after Busch radioed into his crew near the end of a Cup Series race at Watkins Glen asking a doctor to give him a "shot" after he finished the race. According to the TV broadcast, Busch had been struggling with a sinus cold that was exacerbated by the intense G-forces and elevation changes at the New York road course.

Not much information about his death right now, but this is interesting regardless. I never considered that g-forces could make a sinus infection worse, but it makes sense.
