Here comes the day of the surgery. You are given a general anaesthetic and paralysed. Your friend is about to slit your stomach. Hold on! You can still hear them! You were not put into sleep and what makes it worse is that no word can come out of your mouth nor can you move a little bit of any part of your body and you are totally aware! Here comes the incision...
The story here is what happend to Hayden Christensen in the movie "Awake".
They have an official name for this "anesthetic awareness". It means you are clear and aware in your surgery with all the senses as a normal person which basically means that the anaesthetic fails how ever you can not utter any word! So you are a human that can only take "input" but never give any "output". How terrible is that! Just take a moment and imagine yourself being in that desperate situation...
If we think human beings as this way everybody need to keep learning (the process of taking input) and expressing or applying what they have learned (the process of giving output) to achieve some kind of balance. So that their learning efficiency can reach maximum. The anaesthetic is just an extreme case of too much input and no output at all in a surgery environment. This unbalancing is actually happening in various aspects in our daily life. Think about it. When you came to a new country you have trouble making new friends you are so busy taking all kinds of foreign information but you lack the ability to express yourself clearly. You have a mouth but no longer speak fluently with your heart. You loose your charm cause you cannot have the ability to translate that funny joke in your mind. When it comes to depression that so many people suffer from the essential issue is that they have problems and they don't have a proper way to let that out . Not mention to deal with it. Remember the bat man killer a few weeks ago? Police find a package that he sent to a councilor two weeks before the shooting which include all the fantasy he has but not dare to complete. He did seek for help. Think about other cases where during studying a guy who have read bunch of programming books but never write or debug a program himself. A student who knows all the rules about technical writing but cannot compose a single article. People have a natural tendency to avoid giving output cause when taking input no one is watching or giving you marks. It totally is a lone and zero-risk behaviour while giving output or expressing yourself usually involves some kind of audience somewhere out there who will judge or comment on your "output". If you don't perform well and you happen to be such kind of person who cares so much about what other people think about you you might really have a trouble of giving "output" !
