But seriously,

I know the uterus is a tough muscle but how many can one woman have without it taking a toll on her body? I mean I grew up with a Catholic mom who believed in not practicing birth control but she only went up to 5 before her uterus gave out!

I would imagine that after that many kids, she doesn't even go through labor. They just drop out. I also suppose that since she has had so many pregnancies, her fertility will last way into her 50s. She'll have grandkids older than her own kids.
