The degree of bravery dictates how much 'staying power' you have to holdyourself and confront the object in question, where one with a lesserdegree of bravery will 'let go', 'relinquish', give in, turn away, or give up sooner. In this way, the higher degree of bravery is seen to correlate with holding fast and steadfast for a longer duration - ultimately allowing them to do what is necessary to win, influence, or rectify the powerful situation and complete the actions deemed heroic. It can be viewed as a point on determination and the longer one can remain resolute and unfaltered in the face of the external influence, the more they can get done despite it's power - ie. they are affected less due to being able to hold their own, despite the immense
effect the influence should have on them.
