Viability before 22 weeks is zero. There is no dependability. The body cannot depend on anything and still survive at that stage.
Really? You don't need me to refute your reasoning. Just walk to the bathroom and look in the mirror. You will be looking at living proof that a 22 week old baby can survive in the right environment. You were once a 22 week old baby.
We all are dependent on the "right environment". We are all viable or non viable depending on environment at any point in our lives since conception. Our age has NOTHING to do it. How long would you survive in space without a spacesuit? Are we supposed to write you off reasoning, poor 'ole Sloppyjoe, he just wasn't viable? Or, should we investigate the events leading up to you ending up outside the spaceship without a suit?
