How does the woman do it?!

Michelle Dugger, you know the mom of 20 kids! My uterus is KILLING me and this is my fourth! Could you imagine how PAINFUL carrying your 16th pregnancy must be?!?!?!?! I love kids too but not that much LOL! I just can't imagine a uterus SURVIVING all that, let alone a woman. She's so chipper and cheery...she must be doped up ;0)
