I just read about a thirteen year old Croatian schoolgirl who slipped into a coma. Luckily she came around quickly and amazed her Dr's with a full recovery. The one quirk here was when she regained consciousness she did not speak in her native language. She had been studying German at school, but awoke only communicating in German, fluent German! A couple hundred years ago they would have considered this a religious event, perhaps a miracle. Some cultures would have minimally exorcised her, others may have stoned her or attacked her for being possessed, a witch, or some other aberration. Luckily advances in science may save us all, but this may also chip away at traditional beliefs. In the US right now there is a right wing lunatic fringe calling them selves the "tea-party".
If they had things their way, they would like to declare science sorcery! "STONE THE GIRL WHO SPEAKS IN TONGUES"
