I honestly think, gradually becoming more and more aware of how different (and better) men experience life and aging has helped me. If they can get away with being seen as "silver foxes", or "salt and pepper', or somehow elder and distinguished and worth listening to, then so can I! I am just as valuable as them, and I will not absorb any more of the patriarchal message that women are somehow lesser as they age (see "crone", "hag", "witch" "old bat" etc. it's all a tool to put us in our place... It's not our place any more!).
Also, following a lot of empowering insta accounts can give food for thought. Around perimenopause, disability, and the beauty of aging female bodies. Making it normal, to counteract all the Hollywood perfection and filtered, altered faces and bodies. Old women have lived. Old women have shit to say. Old women are poets, artists, mothers, grandmothers, activists, dancers, solicitors, smallholders, shop workers, they like food, sex, pets, laughing, and being visible. To reduce all of that to merely greying hair, soft stomachs or frown lines is a fucking tragedy, to me. We are so lucky to be alive!
