I've got something. I know many NT's even who are between 30 and 40 who are single, go out a few times a week trolling the bars to get wet, some of them are decent guys but they've really abandoned all hope because for whatever reason - while everyone else was marrying - they weren't and they've come to the conclusion that no one worthwhile is left after 25 or 27. What's worse, even if they did meet the right person, I get the impression they'd feel like too big of skanks to deserve her. Nothing works long term, they don't try, and any night that doesn't end up in a girl's pants is a wasted night. I start thinking of Gigolo by Van Halen and just shudder. I'd have to say that's an even darker night of the soul than being chronically single through that age range, where in the later case you at least aren't pissing yourself away.
