I beg to differ with the people who say age doesn't matter. Sure it does. It should not be the only criterion to choose a mate, but it sure matters.
Of course, I assume we're not talking about a 44 year old man who marries a 22 year old girl because "both are in the Truth" and there are no other "suitable" guys around, other than disgusting worldly people. Ah, and there are many chicks in the congregation; didn't Jehovah say that He would provide? My thoughts on this matter are, some men in the religion have found a "holy" (holy cow!) way to justify their going after the younger. Just as the rest of the people would do, only without the claim that this is done to Keep Yourself In God's Love, and those firm breasts of hers are not important at all. Yeah, right.
I am of course open to believe that some of the guys above would indeed marry out of love. I'm not that cynical yet.
Now, in a more general perspective, a 44 year old man knows full well that he's not in the same stage of life as the girl. He's trying to play with the advantage of his greater experience in life. Of course he's aware of the fact that the girl may not like his body that much, but finds compensation in other areas, such as, for example, his being better established in life, and his NOT being like 22-year old men; and he plays that card. He gives her security (including financial security) and "position", and gets youth. Most likely he won't like the same music, dislike the friends, and will have a totally different perspective of life; but that doesn't matter.
He will also be afraid of her sleeping with someone younger, which is maybe why he will be quick to impregnate her. That will keep her quiet.
When our 44 year old hero is 66, the girl will be 44. I'm sure most people will agree that they will be having some problems then. Like, for example, her feeling that she's in her sexual prime while he's somewhere else, and her feeling that she's now the caretaker of her grumpy grandpa, who will also be aware that she's now in better shape than ever. Other men will know that, too. And those twenty years of life together will have some weight of their own.
Now, at that age, suppose the children have left the home. What about the feeling that the nest is empty?
A 44 year old woman with a 22 year old man would be an absolutely different thing. I am sure she would be way, way ahead of him in life, way more knowledgeable, way smarter, and of course sex would be the main reason behind the relationship, from her side. From his side, the discovery of a new sexual world, and money. Or money, simply.
Like I said, I agree that some people could really be in love. But they would be very few.
I wouldn't say a word if the difference were, say, ten years.
