Some alleged "scientists" and researchers try to justify a preference some men--by all means not ALL of them or even most of them--of younger women by claiming that is the reason menopause exists.
As if men don't through the decline in fertility themselves; they do, and that decline has been linked to a host of birth defects, including autism.
What a bunch of utter bullshit, and it peddles the bullshit notion that women are "used up" by the time they hit fifty.
Menopause is a result of an increased lifespan, and an aging body cannot handle the stresses of childbirth.
It sounds like these morons want something to back up their OWN preferences.
