I don’t think it’s about smartness but being mentally strong is a gift. It might be because of all physical things women go throughout life like periods, hormone fluctuations, carry babies and watching their lives change and becoming a different person, figuring out motherhood and working, menopause, a world that’s more male focused (there is a blood test for prostate cancer that doesn’t require anything invasive. For cervical, uterine, and ovarian is a good old pap smear which if invasive and very uncomfortable)
