U.S. law regarding abortion isn't going to change much in coming years. People are now arguing about what to do about the edges of the issue.

The author, Cynthia Isabell, doesn't approach this from a religious perspective. It's all based on her understanding of science and her experience as a nurse.

No matter where you fall on this issue, it's worth a bit of your time.
