Moving means often that your wife or husband must sacrifice their own career. If your partner earns more than you is not a really smart strategy. In any case can be a very selfish move.

Claiming that you must travel to be able to talk with other people in order to "complete yourself" (whatever it means) or to be exposed to the world is simply moronic in the age of internet.

This is still just a fossil remain of the old times where scientists were supposed to accumulate curious objects and to entertain their noble sponsors with the tales of their travels in the longer European winter, or to make reports and act as part-time spies in different countries. Hence the obsession for frontiers.

This means than the closer you live to the frontier, the better scientist you will be. Could find work at 2Km of home and earn some extra points in the checkbox of "had being humbled by the exposure to other cultures" that can be decisive later.

But me... nope. The problem that I was interested in didn't required to cross a stupid frontier (that in fact does exist only in paper currently). I'm not the kind of good scientist that "travels"; just worked at 1000 Km of home
