No matter where you are or what the moment is there will always be a moment where first aid skills are needed. It could be a co-worker or relative or your buddy when you’re out shooting. What do you do? Sure you could pull the movie routine and rip your shirt in slow motion, or you could pull out your kit and apply just the right bandage for the moment. Maybe you are up high in the mountains doing some back country skiing, at any moment you should have the skills and understanding on how to fix any situation.
