[Livia]

Those horses are some of the best cared for, best fed animals in the world. No one wants horses to die, and I expect the owners, trainers and jockeys feel the same. If the horses didn't want to run, they wouldn't. You'll notice when a jockey falls, most of the time the horse goes on to finish the race. I think there are many worthy animal welfare concerns, but that this isn't one of them.
