This is a great thread.
Swimming and hairiness: I'm getting far more laissez-faire about my body hair when I go swimming, mostly because I forget to do it, and then go 'ah, fuck it, my legs will be underwater anyway and if anyone's staring at my pits or bikini line then that's their problem' 
My life is already pretty non-comformist. I'm used to being out with my children during school hours and getting comments (nearly 100% positive, I have to say, but comments none-the-less); I'm used to them looking unkempt (or 'free range' I like to call it
); I'm used to breastfeeding in public...even a toddler .
I just think I've got to a point where I mostly really don't care what people think of me because if people think badly of me for not conforming to whatever stereotype they've found for me (like I am a hippy, woo non-vaccinator, but I let my kids watch tv and play on the computer and I don't wear tie-dye and floaty skirts), then that's their problem and I probably am not interested in the opinion of a bigotted twat like that anyway!
So I often wonder why I have such an issue with my hairy legs and armpits myself - I wish I could learn to love them hairy because I bloody hate shaving them!
And wrt careers - it's the desire to be 'successful' that is the issue, I think. Is it just money? Or is it the need to be recognised for an acheivement of some description? We mothers are not recognised for the incredible (IMO) achievement of growing a human being within our bodies, and then, if we breastfeed her, the fact we have continued to nourish her beyond birth. Good parents are not recognised for the valuable and immensely difficult and complicated work they do in bringing up children - all that happens is that shit parents get judged.
As a HEor, people often ask me if my children will do exams etc.; how will they get to university? I always say that I want them to measure their success by what they consider to important. IMO I am a very successful mother - I have, so far, acheived what I want in life. I am happy, I do good things that help people, I work hard bringing up my children. But that's not successful in the eyes of a patriarchal, capitalist society. I'm not a manager of a company, or earning million pound bonuses, or writing award-winning novels.
I'd like to see a world where success is measured by how happy and confident people are in their lives, rather than how much they earn or discover. Then we might see what is traditionally women's work being valued more.
