Since they are in far better physical shape and have access to far more advanced and specific medical care than pretty much all of us( perks of being part of the dog'n'pony show),why are so many of them suddenly keeling over, when what would be expected is for the american population to be facing a societal collapse due to all the people that would be dying left and right before they faced such effects, given the poor physical health of our population ?

I'd be expecting a massive slaughter, impossible to spin or cover up before the athletes started dropping. What gives ?
