English Speaking Women Have Bigger Jaws?

Women from English-speaking countries often seem to have stronger jaws then women from non English speaking ones because speaking English forces you to use many more muscles in the jaw area than in other areas. Particularly, speakers of American English need to move jaws more than say, German women or Russian women whose languages require less mandibular movements. This may be one of the reasons why many American women are not seen attractive by foreign men- the jaws are too big, almost horse- like. My grandmother would often notice and tell me that there was something horsish about the faces of American and British people.
