do not fret as i go into battle; for i am used to the scars of war. do not fret as i go into battle; for it is not a bore. do not fret as i go into battle; for i am used to my foes. do not fret as i go into battle; for i am used to my woes. do not fret as i go into battle; for most of it is in my head. do not fret as i go into battle; for the enemy is also in my bed.
