That has cheered me up no end.
I don't think my personality is going to let me fade into 'age-appropriate' clothing/behaviour - and I need more Helen Mirren's around to ensure I don't look like an eccentric.
For what it's worth, I am also massively cheered by the fact that a lot of 'women in rock' are performing/re-forming after having had initial success two or three decades ago.
We're going to live, and work, for quite a while. I think we have to accept the fact that the sexist idea of fading into old age would mean being self-effacing for twenty/thirty years. It's a bizarre idea: a kind of ideal of feminine demureness that is foisted on older women after it has been thoroughlly shattered for the sexist nonsense it is. Yet we are supposed to meekly sign up for it, after we have lived (some kind of) liberation.
I know that the above ideas are not new - I remember reading this stuff as a student some 30 years ago - but they are very, very tenacious.
Looking at that picture also makes me realise how much a woman's sexuality is something that matters. It is, for good or ill, tied to a sense of self, to visibility, to life-presence. I know that I, for one, have always been quite critical of that link, but I think it's interesting, and quite crucial when it comes to thinking about women and ageing.
Anyway, I like that picture. I also read a bit of a biography of Ian Dury and Helen Mirren does come across as someone who is a splash of petit-grain and orange blossom in the world.
