When I'm not writing this blog, I work a regular 9 to 5 as an editor. It's a real Clark Kent/Superman situation, minus any of the secrecy, derring-do, or general excitement.
The reports I edit evaluate people's skills for particular jobs. Sometimes, when the scores are very low, it's much more difficult for the writer to put a positive spin on the results.
In one of my favorite examples, the paragraph described the person's inflexibility in depth. Then it ended with this statement:
Adapts to only the most obvious cultural differences, such as time zones.
Time zones!
This person is so set in their ways that, when placed in a new culture, they aren't going to try to learn the language. They're not going to embrace local customs. They're not even going to wear a piece of traditional clothing. The best they can manage is changing their sleeping patterns to accommodate their physical location on the surface of the earth.
I'd say that's the bare minimum amount of adaptability that anyone could expect of any human being. Jet lag aside, we all do eventually synchronize with the rising and setting of the sun.
No special skills required.
