"Brain freeze" I thought was attributable to the trigeminal nerve. Richard, I'm stealing your joke about the Vegas nerve!

Why is it that, because I'm female, I'm expected to dislike math and know nothing about cars? Both of which are true about me - but my second-youngest niece, who is a high school senior, LOVES math. Sudoku puzzles stump me - give me a crossword any day! - but she does them in ink. Drives me nuts. I know of two other young women who are the same way.
