　　No one wants to see a racehorse break down. The toughest trainers and the most anxious fans seem to agree on this much: A horse has to win, but nobody wants to see one die trying. That such a breakdown is sad news for the owner and the jockey, the person who feeds the horse and exercises it.

　　At the medical center where Barbaro was being treated, people left signs for the little horse, expressing their love for him. Since Barbaro's injury early in the Preakness Stakes on Saturday, the reaction of strangers to his condition raises a question: Why do people care so much about the fate of an animal to which they have no personal connection?

　Barbaro was operated last night, but his fate remained unknown. If he survives the immediate injury, he will face months of recovering.

　The image of jockey Edgar Prado leaning into Barbaro's shoulder to help him stay upright reminded people of the photograph from 1975 showing Jacinto Vasquez leaning against his injured little horse, Ruffian, and keeping her from going down on the track.

　Ruffian, another competitive little horse, was euthanized（使安乐死）after serious injuries early in the morning.

　Horse racing is as competitive as any sport ever invented. Horses are like children, and they cannot take care of themselves. They need people to provide them with water, food and shelter.

Perhaps the real miracle - the one that matters to all of us, whether we know it or not - is that so many of us are still capable of caring so much.
