I had a total hysterectomy at 42 due to heavy bleeding and fibroids causing anaemia. I went straight onto the lowest possible dose of oestrogen only HRT - and have been on it ever since (I'm now 74), and have been told I can stay on it 'til I die provided I keep an eye out for breast cancer.
The HRT, it now appears, helps amongst other things to maintain a better memory, protects against dementia and osteoporosis and isn't the demon it used to be thought. Like Nannynoodles I did try to come off it a couple of times years back but the resulting menopausal symptoms weren't good so my breaks were short lived. (I wasn't a nice person either. So much so that my DH asked me to go back on again!)
I feel like I lack basic general knowledge
