After the decades of agonising menstruation, I welcomed and more or less sailed through the menopause. I didn't do HRT but used something for vaginal dryness.
I did some radical things with my hair, to get rid of the red/grey look and went lighter to mix in the grey, but with a lot of unnatural looking stripes.(at my request)
This went on for some years until I decided I was grey enough to just leave it. Sometimes I go pink or purple, now my hair is light enough.
Invisibility is a mixed bag. It is a relief to be relatively free from the male gaze but there was a lot of ageism in the workplace. But I soon got to the not giving a fuck stage, which is one of the best things about ageing!
The weight gain was a bugger and I still carry excess weight. I can only do gentle exercise due to heart issues, but I am going to do wegovy or something at some point.
I have the same story as some of you, with a hysterectomy coming soon, so I will have get through that bit first.
I'm getting wrinkly at nearly seventy but perhaps because I've always moisturised and not smoked, it's not too bad - yet.
I eat reasonably healthily and take vitamins and supplements, including one for healthy eyes and one for hair. I don't drink a lot of alcohol and try to remember to drink loads of water.
To age well, it is important to keep some neuroplasticity.
I have a left handed day every week and learn new things, with online lectures and reading. I do puzzles and write, paint, bang a drum, have days out, etc.
The key is doing or learning things outside your comfort zone, or outside your normal experiences.
