@ossobuco,
On travel, a matter I've long considered a luxury, people become expatriates for different reason, including suddenly becoming a refugee. How to tackle that? There could be a community about adjusting to a whole new life. This sounds fuzzy since it is fuzzy in my mind, but so many people over our lifetimes have been wrenched away from where they lived. Or the opposite, moved far on purpose.
I suppose that is academically called sociology.. which would fit in with (I think it was an idea by ehBeth) a grouping with such academic titles.
