I am disappointed to see the top comment here criticizes this as "survivorship bias." Maybe the survivors have something useful to communicate that can help others survive what looks "impossible" when you first run into it? Maybe that's the point?

Though this probably shouldn't be exactly a surprise to me given how much shit people give me any time I try to talk about getting well after doctor's basically wrote me off for dead in some sense. No one wants to learn from that either and I honest to god don't get it.
