In this situation life was all about suffering as the captors took away absolutely everything from the prisoners, belongings, families, friends, even their names by giving them numbers...except they couldn't take away that one last choice. They couldn't take away the choice regarding how they dealt with that suffering. The choice prisoners made towards their attitude to their horrific suffering literally dictated whether they survived through the war or not!
So there we are! No matter how bad your suffering is you still have the choice as to how you deal with it. So make that count!
