Conversation:
I am a night owl, I can't seem to make myself go to sleep early, I always end up staying up really long.
Oh I see!   Did you know the night owl's opposite is a lark, or early bird?  They go to sleep at a time considered early, and wake early.
I understand, it' hard to wake up early during the day.
Ah yes. Oh by the way, there is a military war sleeping method to fall asleep fast.
I never heard of it. Can you explain that to me?

Response: Of course, to fall asleep fast using the military war sleeping method, count 100 backward in coffin position.
