A small military unit marched several kilometers through a
desert. Then it’s commander let his very fatigated men rest. He
said to them: “Who is not able to march further should step
forward!” All steped forward in spite of one soldier. The commander
spoke to him: “You are a brave man. I shall report you for a
promotion.” The soldier answered to his commander: “Its not true
that I am able to march further on. I did not steped forward,
because I cannot step anymore.”
