astrobortology
Is the study of astro-abortions. Mothers who are deciding to or deciding not to have an abortion might look at their future baby's zodiac symbol and derive from their possible nature wether they will be a good match for her or the already existing family.
I was reading my Astrobortology Pamphlet and have come to the decision to keep my fetus because he will make a great sibling for my already 2 year old daughter
