According to a recent study conducted by Nobuo Masataka at Kyoto University, women on their periods are better at spotting snakes than when they're not. That...wow. I've come up with a lot of studies before, but NEVER anything that involved hanging around a bunch of PMS-ing women. You're a sick man, Nobuo.
[Researcher Nobuo] had 60 women look at a nine-photo grid featuring eight "neutral, non-scary" flowers and one snake shot. The results showed that they could spot the snakes faster during the "luteal" (aka PMS-y) part of their cycles, suggesting a biological mechanism that can "help pregnant and potentially pregnant women stay safe."
A biological mechanism to help pregnant women stay safe -- or -- OR -- a biological mechanism to help women identify wieners and scream at whoever they're attached to? "Ahahahahhaha -- there is NO WAY your girlfriend's letting you sleep in the bed tonight." Already rolled my sleeping bag out on the couch.
Thanks to Johnny Freakin Call, who understands women on a level nobody without 'Freakin' in the their name could even comprehend.
