PMS

"We know that the variables in a woman's environment are much more likely to cause her to be angry than her hormones, but when she attributes anger to hormones, she's absolved of responsibility or criticism. "Oh, that's not who she is. It's out of her control." And while this can be a useful tool, it serves to invalidate women's emotions. When people respond to a woman's anger with the thought, "Oh, it's just that time of the month," her ability to be taken seriously or effect change is severely limited."

"So who else benefits from the myth of PMS? Well, I can tell you that treating PMShas become a profitable, thriving industry."

"Since 2002, Midol has marketed a Teen Midol to adolescents. They are aiming at young girls early, to convince them that everyone gets PMS and that it will make you a monster, but wait, there's something you can do about it: Take Midol and you will be a human being again. In 2013, Midol took in 48 million dollars in sales revenue."
