It turns out that studies are showing that there could be a genetic reason why some people feel trapped without their next trip on the calendar.
Wanderlust could actually be embedded in the very DNA of the adventurer.
The gene is mutation called DRD4-7R and has been nicknamed the Wanderlust gene.
DRD4-7R has been associated with heightened curiosity, risk taking, and restlessness.
In fact, this gene could be the reason behind the extensive migration of the human species out of Africa and across the globe.
