The no-holds-barred memoir from kickboxer Mark "Fightshark" Miller, the only professional fighter in history to return to the ring after open-heart surgeryIn 2007, Mark Miller was a rising star in professional kickboxing, until a routine physical uncovered a serious condition that required open-heart surgery. The crisis helped to temporarily reunite his fractured family and made Miller more determined than ever to return to the kickboxing ring. But within a year, his parents and brother were all dead, and Miller's fragile optimism imploded, sending him into a tailspin of drugs and alcohol.Pain Don't Hurt is a story of incredible tenacity, dedication, and hard work—how one fierce competitor overcame repeated obstacles to realize his dreams. Miller recounts stories ranging from his childhood spent in the Steelers locker room to the surprising life lessons he learned from other fighters to his triumphant return to fighting in a Moscow kickboxing ring. He talks frankly about family and fatherhood—of the hard lessons about masculinity and violence learned from his abusive father. He also offers an inspiring, exciting, and frank account of the fights—both in and out of the ring—that have shaped him.A deeply personal account of guts, blood, and glory, Pain Don't Hurt pays tribute to the never-say-die spirit embodied in a man who refuses to back down, no matter the odds.
