"On the bright side, the longer your marriage lasts, the less likely you are to divorce."

Emmm.. Not too surprising, is it? Divorces kind of tend to terminate marriages early.

It's not surprising, but it's not logically inevitable.

Suppose every couple divorced exactly on their 50th anniversary if they were both still alive. Then a couple that has been married 49 years is almost certain to divorce, whereas a newly married couple has a reasonable chance of dying first.

I believe the point being made here is that for a given couple on a given day, the length of their marriage dictates the probability that they _will_ get divorced. Almost like a hard drive where MTBF increases as the drive is used.

A dark re-twist to the technological adoption of "infant mortality rate".

I should stop thinking of such connections.
