Not exactly within the topic of FAK upgrade, but not outside the subject either.
One time I injured my arm bad, and had to use one hand to put a gauze pad and wrap the arm with gauze roll. It wasn't easy. It was both frustrating and funny.
So, how do you aid yourself in such a situation?? And are there specific tools to help in "self-help" scenarios that are different from when someone is helping someone else ??
One example is adding a mirror to see yourself if you have injury in the face.
