We have all heard the terms before.  Wanderlust, the travel bug, nomads, vagabonds, wayfarers, drifters, and globetrotters.  All of these terms are used to describe, to a varying extent, people who suffer from one thing in particular, and that is an addiction to traveling.  Once the travel bug bites you, it is a very hard thing to let go.  The excitement that one can get from traveling to new places and experiencing and learning new things can give you a rush and fulfillment that leaves you craving for more-and-more.
