CALAMITY, n. A more than commonly plain and unmistakable reminder that the affairs of this life are not of our own ordering. Calamities are of two kinds: misfortune to ourselves, and good fortune to others.
We are coming to understand health not as the absence of disease, but rather as the process by which individuals maintain their sense of coherence (i.e. sense that life is comprehensible, manageable, and meaningful) and ability to function in the face of changes in themselves and their relationships with their environment.
