"When you fell in love, what were you thinking? Perhaps you weren’t thinking very much at all, because you were swept away by passion, romance, chemistry, and the promise of a joyful future with your loved one by your side. You and your partner may have pledged privately, or in front of witnesses, to love and honor each other “for better or for worse, in sickness and in health.” In all likelihood, however, neither of you gave much thought to the “for worse” or “in sickness” parts of that loving contract. And who could blame you? When you’re in love and in life, why imagine darker possibilities?"
