A WARRIOR WHO FOUGHT FOR LIFE
When Mark endures cancer at age eight, he toughens up and battles that shape-shifting nemesis for fifty-seven years. To fight back, he achieves PhD degrees in exercise physiology and sports psychology, cofounds one of the nation's first cardiac rehabilitation centers, and demonstrates superhuman resilience with extreme feats—confirming the restorative power of positive risk taking.
With Jody, his undaunted partner at his side, he leaps nine stories from a bridge into a river; dives underwater nonstop for over forty hours; free falls one mile during his first skydive; swims 375 miles from Kansas City to St. Louis in the Missouri River while fighting hypothermia; and scales the tallest skyscraper in Denver to support medical research. Through all these rigorous tests of will, he confronts four cancer recurrences with the courage and resolve of a warrior.
