'But as Sylvia hit menopause, the filters came off, her irritability increased, and her anger wasn't headed for that extra 'stomach' anymore, to be chewed over before it came out. Her ratio of testosterone to estrogen was shifting, and her anger pathways were becoming more like a man's. The calming effects of progesterone and oxytocin weren't there to cool off the anger either. The couple never learned to process and resolve their disagreements. Now Sylvia confronted Robert with regularity, venting decades of pent-up rage.'
