Create a realistic image of a woman who is 40 years old. She has a confident and calm demeanor, with a gentle smile. Her skin shows subtle signs of aging with fine lines around her eyes and a natural, healthy complexion. She has shoulder-length, dark brown hair with a few strands of gray. Her eyes are warm and expressive, with a touch of wisdom. She is dressed in a casual but elegant outfit, like a simple blouse and jeans, standing in a softly lit, modern living room. The background is slightly blurred, keeping the focus on her face and expression."
