Women blink nearly twice as much as men.

Blinking is a reflex that is started by a sudden noise. Studies show that women react more quickly then men to these sudden noises, and blink both twice as hard and often as men.Another interesting piece of data; lesbians will blink less severely than heterosexual women, and gay men will blink more severely than heterosexual men. Because blinking is a reflex and isn\'t learned, some argue that the rate of your blinking can determine whether you will grow up to be homo or heterosexual.
