    I’m pretty sure that women start to have periods at the age of 12-16

    I think a simpler way to think about it is that a woman has a period for roughly 1/4 of the year (1 week on, 3 weeks off)… if you have your period for about 40 years- thats about 10 years of bleeding.

    I believe women beg God to have their period cycle only every 20 years… well not gonna happen.
