i really don't see it as any different now...
Well I always loved mechanical things. I didn't like dolls, except 1 I loved (she talked and moved her eyes!) and I could have liked a Barbie (adult). My main thing was cars, matchbox cars w/a mobile city and making roads of my own in the yard. And I grew up w/Dad going to train shows and museums; I loved getting the sticker books and all, and playing w/Dad's trains at the time. Not sure if that was his influence deliberately, or genetic (his whole family - mostly males - is high IQ and very much scientifically inclined).
But that's me. I've always known myself as not liking that froo-froo girly stuff.
The thing is to have the opportunity. It's OK for our groups to be different on average. The important thing is we're looked at as individuals and allowed opportunities.
There is virtually no limit on any of us, regardless of our groups. I'm a mechanical engineer. I had that opportunity both for college education and work. That's all I really care about. I don't care that most women don't have the aptitude for engineering; I do, and no1 has stopped me. That's all that matters.
