Why Fall Asleep Quickly?

On the battlefield, if you don't sleep, you will quickly feel exhausted, make wrong decisions, feel burdened by your mission, and become a liability.

1. Stretch your body
2. Relax your facial muscles, slow everything down
3. Relax your upper body
   1. Lower your shoulders as much as possible
   2. Take a deep breath, then exhale slowly, releasing all tension
   3. Relax your arms. If they are not relaxed enough, tense them first, then let them relax
   4. Relax your forearms
   5. Relax your hands
4. Relax your legs
5. Think of nothing at all
   1. Keep your mind calm. You can do this by holding a still image in your mind
