Women tend to be more intuitive, or to admit to being intuitive, and maybe the hard science approach isn't so attractive. The way that science is taught is very cold. I would never have become a scientist if I had been taught like that.

Chimps can do all sorts of things we thought that only we could do - like tool-making and abstraction and generalisation. They can learn a language - sign language - and they can use the signs. But when you think of our intellects, even the brightest chimp looks like a very small child.

I don't think even when you find a person, you can be completely honest, ever. There's still pieces of you that you don't give away. I do believe you always need that place where it's just you, your thoughts, no one else's judgment or anything.
