Context is everything here!
I've been hearing about the invisibility of the older woman from my mother for YEARS! But as an artist she has always been highly visually attuned, as a beautiful woman has long been on the receiving end of attention from men who were attracted by her looks, and as an extrovert she relishes attention and interaction with all kinds of people. As her looks have 'faded' as she puts it, and with some weight gain, she no longer experiences the same social traffic and this in turn affects her sense of self worth.
Though I like beautiful things, I am more experiential (about 'doing'), as a red head, I got (and still get) a fair amount of positive attention from men, however, as an introvert, I don't really need (or like) a lot of attention!
My 30's and 40's were subsumed with being a 'robot mom'. Frankly, between 2 kids, a f/t job, and a husband who was away most of the week for work, I was invisible to myself! My 50's feels like a blossoming of sorts! I personally feel rather fab, and get just the right amount of external recognition to feel validated!
Yeah, when I'm in a gear store ready to shell out for top-end equipment and the 20 year old SA's is more interested in showing my son (who has no money) the latest shiniest new gadget, and ignores me...I can feel a little 'invisible'. But, I can always take my money elsewhere!
