Some faithful readers of the Nudge blog have pointed out that Econs may not exist on Planet Earth, but they are part of the Star Trek universe, specifically on the Planet Vulcan.
In the classic Star Trek episode “Journey to Babel,” the half-Human, half-Vulcan Spock is joined by his Human mother Amanda and his Vulcan father Sarek. A side plot in the episode involves Spock donating blood to save his ill father.

Spock: Emotional, isn’t she?
Sarek: She has always been that way.
Spock: Indeed – why did you marry her?
Sarek: At the time, it seemed the logical thing to do.
