My great uncle was a mail carrier for decades. I scored 24 and 27 on the Wired Magazine test, but when I think of him, he'd be mid-30s at least. He has a few friends, but hates crowds, and will just out of the blue start talking to a person after no contact for weeks. When his older sister died last year, he admitted to me that she'd really held him up a lot - she would always call him to go out to eat and stuff, and all his life she was helping him like that. My great aunt never really thought about it, but I do think my great uncle has AS, even if I'm just borderline between NT and AS.
He really loved the work. But, I do think IT is even better nowadays. Mail carrier was among the best he had available, though.
