"It happened to a teammate of mine—a very good friend whom I had known since we were both boys, playing ollamaliztli together in the streets," Fede said. "I broke both legs in a game at the Tenochtitlán stadium and had passed out from the pain. But I regained consciousness just in time to see and hear what happened to Lorenzo down in the first-aid room. The MedíCarros let him die. One of the paramedics wanted to try to revive him, but the other said that the priests had insisted on a heart that day, that the game was almost over, and that my friend was already near death and was the best candidate. And so they waited until Lorenzo’s heart had stopped beating, then cut it out and ran it up to the temple. I was shocked, but pretended I was still unconscious. I knew that what I had seen and heard would cost me my life."
