And let them all play hockey!!!
Women playing men's hockey never is fun. I recall playing on various 14-u teams where women 16-17 of age were allowed to play -- you have a very mixed mental reaction when a female cross-checks you from behind. If it were a guy in her stead, he would be bleeding from the nose and eating ice.
Combing boys and girls for sport discourages many girls from participating. This in turn fuels the obesity epidemic which in turn drains the health system and impacts negatively on economic life. Promoting good health in in the national interest. It is amazing how some people overlook this factor.
