I enjoy moving to a different country almost every year, thanks to being a digital vagabond.
I am taking a wild guess; The past 400.000 years of evolution in which our bodies and minds adapted to a nomadic lifestyle may still resonate in our genes. Only since a few thousand years were a majority of my ancestors bound to one place and this short period is unlikely to have had any genetic impact. A lack of constricting possessions is surprisingly rewarding (constricting in terms of hard to move). I suspect that this reward is universal to humans which would imply some kind of genetically predetermined preference. But it is just a wild guess.
Yet I feel with my son's first birthday approaching this lifestyle will be hard to maintain.
