In the August 2008 issue of DETAILS magazine, Greenfeld described zombie marriage and wrote that being in a zombie marriage could help your marriage become stronger down the road.
He writes that you have to survive the zombie phase and not end up killing your marriage or suffocating it with a bunch of relationship fixes. He recommends that you just leave a zombie marriage alone.
"... the Zombie Marriage is just a phase — and quite possibly a crucial one. For a lifelong relationship to survive its most challenging period, it must enter an unconscious, protective state, so that no matter how many stakes are driven through its heart it will continue to stumble forward ... Because the Zombie Marriage, just like those B-movie ghouls who can be restored to mortality with a few drops of a serum or potion, can be revived."Our term for a zombie marriage is disillusionment. We think that disillusionment is normal and is part of the cycle of romance, disillusionment and joy that married couples experience.
We don't think a zombie marriage should just be left alone. Doing nothing is not a good option when you are in disillusionment. You need to talk with one another about your issues and problems.

I think first-cousin marriage is okay. You said (or somebody here said) that Albert Einstein’s parents were cousins. Now, were
they first cousins? Or second or third or fourth? I notice that an awful lot of people talking about an awful lot of different subjects leave out a lot of details.
Apparently, Einstein’s parents were first cousins, and his second wife, Elsa Lowenthal was Albert’s first cousin on his mother’s side and his second cousin on his father’s side.
