I once had a friend who was diagnosed with terminal cancer, and the news that he might only live up to six months was a great shock to him, his family, and his friends. However, in spite of the serious illness, he was initially determined to look into all available treatments that might cure or extend his life. I think that when you find yourself in such situations, you tend to look up every possible way for hope of saving your life.
As months went on and his health grew worse, I noticed an unexpected change in attitude that came over him. He had also been a happy person with a cheerful personality, but rather than give in to discouragement and self-pity, he took comfort in God and humanity. His talks focused on others rather than himself, and he spoke of the afterlife as something he was prepared for, believing that his concerned ancestors, including his mother and father, were there waiting for him.
