One thing I forgot to mention is that I'm a bit of an advocate of women in science. Perhaps no surprise. So I was therefore interested by this article. I love the quote about men being better at spatial abilities than women. SOME women I think. I know men who take you 3 sides of a square when you know the 4th side is so much quicker. Women have a reputation for being lousy at map reading and 3D visualisation but that doesn't mean all women are like that does it? Like, I suppose, is the theory that no man can multitask.
