Odds?

Lady Shar and I have been married almost 110 years, just not to each other.
My first marriage went over 57 years and her was over 50. So we begin with a good bit of  experience. One of my friends sent a congratulations note with this line: “If this marriage lasts as long as your last one, you will be an old man.” Most of our past was very good.
We are both pretty set in our ways, pretty hard headed, maybe we even be called a bit stubborn. So, what are the chances of this marriage between two septuagenarians working long term? Of course it is too early to do much beside guess, but from this perspective, it seems that we have a pretty good shot at long term (there is that term again) happiness.
For one thing, though we are both fairly (or more) stubborn, we are also smart enough to know that most battles are just not worth the trouble. And we laugh a lot.
We are both more resilient than I might have thought. We both own houses and while neither is ideal for the two of us, we have both agreed that we could live happily in either, though we are keeping our eyes open for something even more suitable.
I hope that is a predictor of good times ahead.
So, while it is way to early to know for sure, we are off to a decent start.
