There is never a generic template that fits all scenarios of life. Life and people are all so dynamic that we can only attempt to generalize certain assumptions based on trends. Well, when some women turn 40 or 50, something major shifts in their personality. I hear this is also when some men come out of the closet to declare that they are gay or want to be openly polygamous.
Their wives and onlookers may be left astonished not only by the new revelations but also by the I don't care attitude they show towards the opinions of others.
