Viability has been pushed back a little , but not as much as you might think . In Roe v . Wade it was set at 28 weeks , but noted that it could be placed earlier , at 24 weeks . Now something like 90 % of infants born at 2627 weeks will survive , but that outer edge of 24 weeks is still the limit . I think until we have artificial wombs that limit will stay around 2324 weeks . I believe lifesaving measures are generally not even tried if the fetus is 22 weeks or less . <| sep |> Throughout my fimfic life I ' ve been seeing these stories and their infuriatingly vague descriptions in the feature box . I have to say , the descriptions ' vagueness turned me off incredibly , to the point of annoyance when a new one appeared up there . It felt like I was expected to be immediately interested just because it ' s Rainbow Dash and it has a fancysounding name and has this pretentiously empty description . I am certainly curious about what actually goes on in them , what the heck could be so interesting about how Rainbow Dash flies east . But not curious enough to read them on my own . Their presentation has made me so biased against them that nothing can sell me on them at this point . I may be more curious about just what drew people in in the first place . Why did you give them a chance ? Or was there already a lot of views and high ratings when you saw them ?
