The 40s have been a strange combo for me (I'm in my late 40s now.) While most of my peers have children in college or out on their own, and are starting to get some time to themselves, I have two kids in elementary school. I am living the life of a mom with young children in the home, even though I am grandma-aged for the rural midwest area in which I live. It has kept me young in some ways, I guess. My interests usually dovetail with those of a somewhat younger generation (gaming, etc.)
I'm definitely older, and, obesity aside, there are the usual changes in appearance happening as women get into middle age. I'm a cerebral person, so I have been viewing how the world treats and sees aging women with interest. Sometimes we become invisible to people or at least that is what I have been observing. Despite this, I have always loved whatever age I am, and my 40s are no exception! I definitely feel more... confident, settled, peaceful, balanced, etc. I have tackled my weight loss with aplomb - you can absolutely lose weight at 40+ years of age
This is a great age decade, although the hormonal changes can be annoying ;P
