I have read many studies on this topic and believe that while they are informative they do not deal with the cause of this phenomenon. The ‘experts’ explain that the act of speaking stimulates the pleasure zone, in the female brain, much the same as heroin does. But how did this effect evolve? Here is my theory.
When man began roaming our earth, the main role of men was to be ‘hunter gatherers.’ If you have ever been hunting you know that the one thing you don’t do is talk. Talking, above a low whisper once in a while, would scare the game away and there would be no meat for your family of tribe to eat.
On the other hand women were back at the encampment doing what women did to contribute to the well being of the family or tribe. They were nurturing the children, preparing food, making baskets or the many of other duties that women would occupy themselves with. All the while they were doing these things, women would talk between themselves, at a rather loud level. Why? To keep the game or, in their case, the predators away.
This phenomenon has evolved to the point that according to every study women, on average, speak between seventeen to twenty thousand words a day.
Men speak about one third of that amount. However men find themselves listening to this constant barrage of verbiage from females. I believe that this is why husbands die about ten years earlier that their wives. They have been talked to death.
