This conclusion presents some closing thoughts discussed in the preceding chapters of this book. The book explains that the stress is on human beings as social creatures who, from the cradle to the grave, become temporary or permanent members of certain groups and institutions and identify themselves accordingly. Many social interactions are direct or indirect encounters with representatives of the various organizations and institutions that make up a society. Some cultural groups are more family oriented than others and consequently not as active in extrafamilial society. Among the problems that extend beyond the individual and encompass entire societies are poverty, malnutrition, disease, crime, war, terrorism, and social discrimination. Funeral rituals and methods of corpse disposal have varied extensively with historical period, culture, social class, and religion. Traditional mourning practices, such as wearing black, restricting one's social activities, and flying flags at half mast, are still seen but have become less common over the years.
