"Bonica's years of wrestling caught up to him. ...Still in his mid-50s, he suffered severe osteoarthritis. Over the next 20 years he'd have 22 surgeries, including four spine operations, and hip replacement after hip replacement. He could barely raise his arm, turn his neck. He needed aluminum crutches to walk. His friends and former students became his doctors. ... Already a workaholic, he worked even more -- 15- to 18-hour days. Healing others became more than just his job, it was his own most effective form of relief."
