It may be more in tune to real life with the older guy with being with a younger gal – just the way of the world it seems. Does not seem to be that unusual to for man to be ten years or so older than the woman. Even in this day and age. Look at many of the couples in the media, entertainment, politics, etc. This is not a hundered percent accurate all the time but a large portion of the population seems to work this way. This theory holds pretty solid since the writers for the most part have paired ‘about the same age’ couples and the older man/younger woman, but have not written an older woman with a younger man…at least not that I have seen in "Days" and perhaps just a couple of movies, etc.
