Hmmm. Relocation. I moved from Cape Town to Kansas when I was nine, returned to do my military service there, became an American citizen, went to Frankfurt to the Dresdner Bank and back to Kansas, thence to Buenos Aires and Bancohipotecario, Kazakhstan as part of my work as a Physicist, Murmansk, same reason. Calgary-oil play, Several years intermittently lecturing on Physics which is or is not-depending on how you see itelocation all over the world. Turned down a research position in Xi'an, As part of a UN Atomic Energy group was poisoned in Pyongyang and "relocated" to Sochi-this was before the Winter Olympics had even been considered and next winter (here) and summer (there) I hope to join a group from Otago University in New Zealand to SCUBA dive in various places under the ice in the Ross Ice shelf.
I was/am single so I could pack a bag-I got quite good at it-and was off. Some people would find the changes in customs, food, water, very distracting particularly if you hadn't taken the time to do some research and learn at least the genesis of the language. I thought leaning Russian was tough until a Russian friend referred me to Finnish.....There are home bodies to whom moving to the next county would be a wrench and then there are those like myself who can-and have-said, "Luanda?Wow, what's the air routing to get there. " The fewer "complications" involving home and family you have makes it a lot easier. If you have clinging vines about you who go to great lengths to point out every possible down side, then, just to be shot of them, it's a good idea to get away. Forever. You have to be prepared to accept what you find in situ as what it is and not wish for a shower tall enough for you, one more burner-to make it three-lodgings that would seem cramped to a hibernating bear....etc. But relocating can be one of the most broadening experiences of your life but you must up front embrace the idea for when you get there, turning back can be very difficult and can also besmirch your professional reputation.
