Just the other day, I found out that it's some sort of well-known thing that women's periods synchronize when they live together. Um, WHAT? Okay first, how is that even possible? And second, is this something that all women just know and accept? I had so many questions and so little answers, so I made this video to find out the answer.
First, I asked some co-workers. Five of them said yes, one of them was as clueless as I was, and one of them said no.
But nobody really understood the science behind it, so I contacted a local OB-GYN. He said that there's no science that backs this claim up, and all the studies that did prove it have shown error in their experimental method.
Well, apparently there's no conclusive evidence. But my curiosity was killing me. I needed to collect my own data. I needed to know if this was true! I figured if there's any girls in the world who are synchronized, it must be sorority girls. So I went back to college.
I first asked the four ladies I visited whether they were synchronized. They all told me, "yes."
But I didn't know if they were just saying that or if there was confirmation bias in play. I threw a curveball at them - I had them write down the date of their last period, so I could determine truly how synchronized they were.
Their responses rocked my world.
