What the hell is going on with these deaths

It is all very depressing. Let's not forget that Electrocutionist died of a heart attack a couple of weeks ago, as well. Perhaps all this bad news will be followed by good news: Barbaro is getting better and better; Bernardini proves to be a superhorse; Lava Man proves to be the best gelding since John Henry; the horse slaighter bill is passed by the Senate; and Serena Tune's colt by Vindication wins the Triple Crown in 2008!
