I really like this approach! I am first aid certified for my work and I totally agree that in an extreme situation, I really don't think I could actually help but It is an extremely helpful area to be knowledgeable in. I am not sure if all high schools still teach this but through the physical education most students take in grade 9 they are required to take a first aid portion and become certified. I know most people will have forgotten these classes but I am also an advocate for educational games. I am really excited to see you're approaching. Are you thinking a life-saving game or maybe a puzzle game?
