John Dye quotes:

I want you to know there's nothing... nothing to be afraid of. On one side, there's life. And on the other...there's life, too.

According to physiological law, all natural, normal functions of the body are achieved without peril or pain. Birth is a natural, normal physiological function for normal, healthy women and their healthy babies. It can, therefore, be inferred that healthy women, carrying healthy babies, can safely birth without peril or pain.
