This man was extraordinarily lucky to be alive to tell his story: that for 23 years, they thought he was in PVS state, not realizing that he was actually paralysed but fully conscious of everything that happened around him. This news didn't come from a particularly pro-life publication; it just reiterates how flimsy are the criteria for brain death. It is particularly interesting to me as we now have classes about anatomy, pathology, and inevitably, organ transplant and the polemic around it.
This one is from LifeNews with some commentary on how this episode affects debate about PVS determination and ethical implication.
