I honestly believe it's a fundamental difference between sexes, in general. Sure, there are female mechanics and IT professionals, but there are certainly more men in either business.

However, it goes both ways: teaching is a female-dominated job, like guidance counseling and other emotionally-intensive jobs. It's just the way they work. Again, not to say a guy can't be a guidance counselor or a therapist and not to say a woman can't work on cars. Neither would be true at all. But it IS true that women are better than men at thinking in certain ways, just like men are better than women at thinking in some ways. Not an insult. Just a fact.

Multi-tasking's a good example, as a matter of fact. Something that women, in a general sense, just do better than men, and that's that. There're all kinds of little things like that, actually.
