If you’ve ever had a period, you’ve probably had some amount of pain to go along with it. Guys, don’t give me that look and laugh. I have the perfect comeuppance for you: the menstruation machine. It simulates the pain and bleeding of five days of menstruation. It isn’t mass-produced, but if it were, part of me would be tempted to try it out just long enough to see how accurate this person’s idea of menstruation is compared to my own cycle. No matter what this menstrual cycle is like, it’ll never compare to those who have really vicious cycles and will think this machine’s version of menstruation is a walk in the park. More importantly, it will never compare to PMS, which won’t be fully programmed into a wearable machine for a long time.
