Schiavo wasn't brain dead. Her lower brain was functioning. She didn't need life support except the feeding tube She could have stayed a long time in that state if her feeding tube wasn't removed. Her body was obviously pretty healthy, even after her feeding tube was removed, it took 13 days for her heart to stop. But even brain dead people can last a while (years) on life support. Jahi McMath is still on life support. Sounds like BB is expecting miracles, so this reminds me of Jahi McMath's situation, because they also claim they are waiting for Jahi to wake up despite her being declared brain dead.
