Gottfried, another one of the men interviewed by our University of Chicago team, provides a similar example. As a child Gottfried was very close to his mother, and his memories of those early years are sunny and warm. But before he turned ten, his mother developed cancer, and died in great pain. The young boy could have felt sorry for himself and become depressed, or he could have adopted hardened cynicism as a defense. Instead he began to think of the disease as his personal enemy, and swore to defeat it. In time he earned a medical degree and became a research oncologist, and the results of his work have become part of the pattern of knowledge that eventually will free mankind of this scourge. In this case, again, a personal tragedy became transformed into a challenge that can be met. In developing skills to meet that challenge, the individual improves the lives of other people.
