If Baby does not bid in the womb can not be born ..
bid if the mother to give birth, the baby is born
Without the trauma of birth there is no life ..
If there are examples throughout nature
If a butterfly is not difficult to leave the cocoon
smooths its wings is not and can not fly, dies ....
Then, in the minds of some there is the encoding:
"Give me the food in your mouth and chew it for me?"
