Memory

If we did not have a memory the world would be very chaotic. We would have no idea about anything. We couldn't hold jobs or have relationships because once something would happen wouldn't remember it. If we tried to learn something we would forget why we were there in the first place. It would probably end with people dying early because we wouldn't remember to eat, bathe, or drink.
Clive Waring knows nothing, but whatever was happening before his accident. H has no idea of time or the date. He knows nothing about what is happening in the world. He would have no idea what is going in his life. He has no part in the world around. To anyone, but his wife, he is no one.
I don't see anything different about my memory, I just understand it a bit more. I now understand how when someone says something, I say what, and as they are about to repeat themselves I am already repeating what they said. Which I do all the time.
Flashbulb memories. They are important because they can recall an important event to us. We can recall exactly where we were at that point in time. It is sometimes bad but sometimes good. Like it could help find the killer to a murder and so on and so forth.
