ABSTRACT
People are comfortable and function well only in environments of which they know the resources and the dangers and to which they are emotionally adapted. Even with the vastly increased mobility of the modern world, most human beings today live and die within a few miles of the place where they were born. The hunter-gatherers of the Old Stone Age generally established their camps near bodies of water and in locations where food was abundant. During the Old Stone Age, certain sites close to one another sheltered for long periods of time human groups which differed in the styles of their tools, weapons, and other artifacts. In all industrial countries people of all ages dream of returning to unspoiled nature, there to start a new life in intimate contact with the land. For a few adventurous people, this means life in the wilderness or at least in communes.
