Peri-menopause generally begins in the mid to late forties. It takes anything from four to ten years and the average age for the onset of true menopause (when periods cease completely) is 51 years.
Many of my female friends over forty are feeling daunted by the imminent onset of the 'change'. It looms on our horizon like a gathering storm of ancient soot and carnage. Our air is heavy with anticipation, we're all forecasting doom and it has to stop.
