Conundrum I realize that you have a point but I am thinkin that the answer is most likely the same to the question of why men in relationships let themselves get fat.

I would prefer it is he slimmed down a bit as this would contribute to his overhealth. But it isn't like I don't find him sexy the way he is. I mean, hello, it's how he was when I married him.
