There is an interesting theory to which I will refer when confronted with combined ageism and feminism. Briefly, it proposes that human evolution took a great leap forward with the menopause and female longevity because younger women who were mothers could benefit from the knowledge and experience of their own mothers, who did not have young children of their own requiring time-consuming maternal care, while at the same time, expanding their own knowledge and experience.
In spite of all the grandstanding and absurd movie-making about cavemen hunting sabre-toothed tigers and woolly mammoths – and I wonder what on earth those tasted like – most hunger-gatherer communities (ancient, more recent past and present) relied much more on the gathering than hunting and that was mainly women's work. How helpful it would be if your mum passed on her own carefully guarded knowledge of where to find the fattest berries, how to take the honey without being stung by bees and which plants were best avoided.
Plus ça change, plus c'est la même chose. There are many gransnetters who share their wisdom about relationships, cooking, childcare, removing stains from clothes, saucepans and children's hands, and many, many other aspects of modern life, including, of course, working life outside the home in what is still a man's world, with their daughters. (I am not denigrating mother-son relationships, but this theory is to do with mothers and daughters). We do it instinctively and don't we love it?
