How can a woman's health change once she turns 40?

Doesn't have to. After 40 or by 40 many women are in perimenpoause and will experience hormone fluctuations. Eyesight changes...You may need glasses. You may have mood swings, memory loss that is temporary; you may notice a few wrinkles here and there. But many women have never felt more alive and more valued and free as they mature. Acupuncture/ chinese med can help with hormone changes...A lot!
