59 Viability is usually placed at about seven months (28 weeks) but may occur earlier, even at 24 weeks.<quoted text>
It wasn't a footnote from a medical book, it was part of the RvW decision. THEY used the words I quoted, and I quoted it from this site. Maybe you should educate yourself, because you keep trying to argue what you don't know anything about.
This site shows the RvW decision, and on the page I linked are the words,
"Physicians and their scientific colleagues have regarded that event with less interest and have tended to focus either upon conception, upon live birth, or upon the interim point at which the fetus becomes "viable," that is, potentially able to live outside the mother's womb, albeit with artificial aid. Viability is usually placed at about seven months (28 weeks) but may occur earlier, even at 24 weeks."
RvW mentioned the gestational age, and physicians use the gestational age along with weight of the fetus to determine viability. Viability occurs WHILE the fetus is IN the womb. Not once born and surviving without medical aid as Katie tries to argue.

It's a footnote.
