That Aunt Flo Ruins Everything

Ever blown out your knee while boarding (or skiing) on the snowy slopes? Turns out that your menstrual cycle may be as much to blame as your skills.

According to studies done by researchers at the University of Vermont, women are more likely to injure their knee's anterior cruciate ligament (ACL) during their preovulatory phase of their cycle, which is the first half of the menstrual cycle that begins on the first day of menstruation and continues for about two weeks.

So you may want to plan any ski trips accordingly.
