OK, so... why do girls run?

Tell me if you have observed this; if you have picked up on this or not. The next time you watch a girls or a women's basketball game, check out how they go back to the sidelines for a time out. They jog or even run! The men don't do it. Just check it out. I have observed this at many levels. Girls and women always jog or even run back to the bench at basketball games. It does not matter if it is young girls, high school or college, even pro. Why is this? Maybe to hurry up and get as much time resting as possible? I don't know and I played ball in high school myself. Why did I jog back to the bench? I don't know! If you have an answer, please tell me...why do girls run?
