Although the code of conduct of past warriors that integrate honor, courage, loyalty, respect, and compassion is still very much the same, now the battlefield is different. Many still believe that joining the military is the only way to show warrior qualities, but this is not the case. Though there will always be active conflicts around the world and warriors will be needed to fight and protect, we can be warriors in our own lives by a continuous drive to train and be prepared.

In this case of most training courses, we are measuring stressors as heart rate and external pressure from instructors/ourselves. These all show themselves physically as a buildup of carbon dioxide in the blood. Even if we cannot recreate being in a gunfight, or having our children in danger, our brains typically cannot differentiate between physical and mental stress, and the reaction is the same.
