Clenching Right Fist May Give Better Grip On Memory

I thought this article was neat especially since were were talking about memorization the other day in class. This article shows that those who clench there right fist may be able to memorize information quicker than those who don't. I might actually use this when I study. I look forward to hearing more on this study.
