Brock has had it rough in recent years. But he’s alive and well, relatively so, anyway, considering that his left leg had to be amputated four years ago because of diabetes complications. And because his lower back still bothers him because of the blood cancer (multiple myeloma) that jumped him a couple of years ago. And because he has had a heart condition, stemming, he said, from some contamination in his left leg. And because last November he had a stroke, which, he said, he didn’t know he had.
