I'm sure that's an important component of it. But it is not the whole story.

For example, incidence of clinical depression peaks in the late 40s. This page has a graph:

(I've seen more detailed graphs, but I can't find any right now.)

Also, I read about a study that showed that predictions of husbands having extramarital affairs could be made more accurately based on the age of the wife than on the age of the husband. The authors hypothesized that husbands looking elsewhere for sex, was, in part, a natural response to the wife going through menopause. (I can't find the study now.)
