Femmes talk almost thrice as much as their male counterparts according to Dr. Luan Brizendine, author of The Female Mind. This self-professed feminist states that the differences between the female and male brain explain why women do so. According to Brizendine, females devote more brain cells to chatting and the very act of conversing initiates an inundation of brain chemicals that give women a high akin to heroin. She said, "Women have an eight-lane superhighway for processing emotion, while men have a small country road." However, Brizendine said that whereas men have an international airport for sex thoughts (with their brain "sex processor" that is twice as large in men as in women), "women have an airfield nearby that lands small and private planes." In fact, she observed that a woman tends to think of sex once a day whereas a man does so every 52 seconds on average.
