One wife is quite enough (or more) thank you very much that a mortal man can handle. Let the mormon men die young with coronaries if they want.
When my late wife of 55 years was dying of leukemia, she said, "I don't want you to get married again. If you do I'll come back and haunt you." I replied that I didn't have 55 years to train a new one. I can't imagine having to be with more than one.
