It’s really hard to figure with Kyle Busch. I know that as a top racer, he was driven. Perhaps driven beyond what an ordinary person would be. Whereas many people, perhaps most, would take a couple of days off, see the doc, and get healed up, he was driven to win and he was near the top of his game.
But it is suspicious. Seems like the extremeness of the illness wasn’t apparent last week when he was winning.
I think Pneumonia is a symptom of something worse, not the primary disease, in a lot of cases. But I don’t really know. More or less speculating.
I think it was some months ago that Busch’s wife was at the White House as part of a promotion of IVF treatments. Not sure if it was used on one or both of their kids. Seems like the personal life was a bit complicated also. Racing might have been another dimension of sorts. High talent guys tend to be good at one thing.
