Not to make light of the situation, but your answer is in the body of your post. Use it or lose it. What other first world problem did you have today? 
I was originally thinking we could do an "office pool" and see who guesses closest on the date of closure. Seriously, I do enjoy tests of skill!
However, to keep on the ongoing line of originality(and attempt to outdo it! lol), I will simply wish that the marriage lasts longer than the card. Would it be wrong to place agers or do a statistical analysis of that? 
Seriously, I think I am piggybacking at least somewhat on Arlo's sentiments here.
Maybe you could give an extra injection of health into both the marriage and card(or the card at the very least) with a small purchase if you are concerned about it being closed?

So, what's the over-under on when they might close my Overstock card, which has had 3 x $300 CLIs and one initial purchase, which I returned? I keep telling myself that I need to shop there, but lately, I just don't seem to need anything.

If they decide to close all of the cards you are referencing in a short time frame, I don't think it will look great on the report to have several cards closed by credit grantor. Just my opinion though.

Normally I'd agree with you good fellow, but check out the his scores. I think he has good reason not to be emotionally invested.
dwz55 may be like Jesus, Buddha, or even the Big(little) Lebowski and have a valuable lesson encoded in his message for some. Or maybe not.

well, I can tell right now they closed my Care Credit card shortly after the 1yr mark just recently. ...Each one is different....hard to tell.
Without the OP's inspiration, that would be disheaterning to me, as I was considering getting that card to buold credit while removing the one mercury filling I have. The OP seriously got me to look at credit(and as a reminder, life) in a bit of a different way. For instance, from looking at your sig and that quarter mil(what the? I need to interview you as well someday from looking at those dates), I doubt you greatly regret your decision to use the card, or the reason it was dropped(decent health )?
I definitely am grateful for the data point, but at the same point am stoked by the idea of building credit and health in one fell swoop. Kinda similar to the Seinfeld episode where George wanted to do his 2 favorite things at the same time! (for those not familiar https://youtu.be/qnw8EPvL8HQ )
