Actually preparation for war instills what is referred to as muscle memory. As you drill responses into your head day in and day out, you actually can manipulate your response pretty easily seeing that adrenaline always takes over first.
It is in that adrenaline surge that muscle memory is vital in responding to acts of war rather that depending on reaction. As for your first sentence to your response,"Courage is the sum of all things that make life beautiful..." That makes no sense at all. The sum of all what things. Just the things that make life beautiful? Why would that instill courage? Is it not the discomforts in life that allow us to be courageous? Why would you only suggest that its the beautiful things in life that allow one to be courageous?

Courage, of course, is required in war. However, your initial claim was courage is required in all things that we do. That is why I referenced concern if you had to have courage to defecate. So again another uncertainty arose when you quoted my concern and stated that courage is the sum of all things that makes life beautiful. Poop, in my opinion, is not beautiful and still has no need for courage.

I'm Most Awesome!
