First Aid II

Still no mouth-to-mouth breathing: it will be next week, which will be last first aid lesson -practical exercises. But I have to correct a serious mistake in my earlier post: my theory on lungs was outdated and one should not touch lungs either if they are out. But to be honest, it's hard to imagine a situation when they are out, and most probably there is very little one can help then. But If lungs are still in, but there is a hole in body leading to lungs, then this hole should be definitely closed to preserve breathing function - keep that in mind!
Do you also have a feeling that I'm getting too excited about all this first aid stuff? - kind of freaky again...
