C-Section vs. Natural Birth

I was talking to a family friend who expressed concern because her daughter who is a nurse said she is going to have an elective c-section instead of a vaginal birth. Her main reason is that things down there may not go back to normal and that she doesn't want to deal with labor pain. Now this is the third person I know within the last year that have elected to go for a scheduled c-section and all three women work in health care. How crazy is this, what person in their right mind will go for a major surgery over a vaginal birth? I expected more from these women since they are nurses and are better informed of the risk associated with c-section but are still opting for it without any medical need. Is there something I don't know? Nature intended for babies to come out of the vagina and when there are complications I understand the need for a C-section. But to actually choose c-section over vaginal birth because you don't want your lady parts to possible change after a vaginal birth or to not want to deal with the pain is kind of disturbing and absurd. What next, people wanting to be pregnant but would rather have medical science come up with technology to be able to have a pregnancy outside of the body so pregnancy doesn't ruin their figure or avoid the ups/downs of pregnancy?
