Well, a man had only so many fights in him, to begin with. It was the iron law of the game. One man might have a hundred hard fights in him, another man only twenty; each, according to the make of him and the quality of his fiber, had a definite number, and when he had fought them he was done. Yes, he had had more fights in him than most of them, and he had had far more than his share of the hard, grueling fights—the kind that worked the heart and lungs to bursting, that took the elastic out of the arteries and made hard knots of muscle out of youth's sleek suppleness, that wore out nerve and stamina and made brain and bones weary from excess of effort and endurance overwrought. Yes, he had done better than all of them. There was none of his old fighting partners left. He was the last of the old guard. He had seen them all finished, and he had had a hand in finishing some of them.
