"And viability is an ever-changing concept ( a 12-week fetus was delivered recently in Minnesota , and as far as I know is still alive and doing well -- please feel free to update me if you have heard any other news ) ."
"Actually , I can not accept that claim . Before then , the absolutely youngest ever surviving fetus was deliver at 19 weeks , 6 days . 12 weeks would be a worldwide sensation . I would recommend that you double-check your source . Viability is still defined as the age at which 50 % survive , which still is at around 24 weeks gestation/26 weeks pregnancy ."
