MENOPAUSE how do you know?

One of the major telltale signs of menopause is mood swings which could explain why she has been acting wacky. Some of the other signs and symptoms are hot flashes, thinning hair and sleep disturbances to name a few. Unfortunately menopause can last anywhere from 4-5 years and there isn't really a way to predict what it will be from person to person. I've heard that women who have had heavier periods throughout their lives tend to be in menopause for longer than those that have experienced lighter periods. Women tend to start menopause between the ages of 39-51.
