Good comment. In martial arts, specifically among bushido students, there is the philosophy of "dead awaiting death". Similarly to Cooper's color codes, it denotes a mindset necessary for combat where you accept fully that you may die at any time. It did not mean that the swordsman or spearman was just waiting to be slaughtered, people with this mindset were especially fierce in battle because they gave no thought to preserving their own lives above successfully completing the objective. Back at home, they courted, sang, wrote, and generally lived happy lives, but in battle they were nothing to be trifled with. People with this level of training are able to turn it on and off as the situation demands. People who cannot turn it off usually wind up in mental hospitals.
Never try to educate someone who resists knowledge at all costs.
But what do I know?
