The next time you have a bigpresentation or meeting at work, spend a few minutes in the bathroom beforehandyelling "clear eyes, full hearts, can't lose" in the mirror and come out looking as determined as ever to nail it. It seems that putting on your "game face" is actually a really good thing. According to a new study out of the University of Tennessee, when you put on a "game face," it really can help you perform better. The researchers say, "'Game face' may not only improve performance in cognitive tasks but could also lead to better recovery from stress." What does that mean? You'll be sharper in your meeting and if someone throws out something unexpected, you'll be able to handle it better.
