By the end of the day on February 11, 2001, forty-five-year-old James Lange Amundson was fighting for his life. While on a snowmobiling excursion in his home state of Wisconsin, Amundson's sled was broadsided by another snowmobile traveling almost 100 miles per hour. Married with three children, Amundson suffered a variety of life-threatening injuries, including a closed traumatic brain injury. His battle to survive would be long and arduous. In this memoir, Amundson describes traumatic brain injuries and recounts his journey to recovery. Weaving in stories from his childhood as a member of the drum corps and a speed skating team, as well as a practitioner of Tae Kwon Do, "Unplug Him" narrates how Amundson believes these competitive and demanding experiences contributed to his determination to heal. "Unplug Him" provides insight into one man's fight to overcome a brain injury and communicates the power of a positive attitude when confronted with seemingly insurmountable obstacles.
