We live in a society where most people are mobile. "Tourists" are mobile of their own free will, always traveling to new meetings, new friends, new lovers and girlfriends, new experiences, concerts and sports competitions, and new destinations. We are not looking for lasting relationships, we do not have long-term life projects, much is intermediate, and attractive for a while, until we decide to move on. One I know wrote on FB that it was with great sadness that he had canceled 6 trips, in one day a typical network and academic tourist.
The "roaming hazards" are forced into mobility because their world is devastated by war, drought, food shortages, or flooding. Of course, it may also be that the prospects are so difficult that a dangerous journey, or escape, can seem like the only way out.
