What a great title, what a great film...
I love the scene where it's explained why he needs to hear her voice,
How and why she over comes not being able to hear his
Maybe they could use this film as an example of why it's important to make your choice known in advance, weigh up the possible consequences and - why clearing the airway is so important with first aid and it doesn't matter whether it's solid if it's an obstruction (like water) if you need it out of the way in order to breath.
Why it's less important to attempt to force air into the lungs when there's no blood circulating (which is already oxygenated at the right amount). Mind you, I could be wrong about that, but I think that's correct.
