On Sunday, Chinese Olympic swimmer Fu Yuanhui (she of the adorable faces) blew the sports world's mind when she mentioned that she was on her period during a race.

During an (unsubtitled) interview after the 4x100m medley, in which the Chinese team placed fourth, she apologized to her teammates for her time, saying: "I didn't swim well enough this time. It's because my period came yesterday, so I felt particularly tired—but this isn't a reason, I still didn't swim well enough."
