What was I supposed to do again??

I found a video on youtube that explains how your memory works. It explains why you lose your memory more and more as you get older. The more times you study something the easier it will be to store it in you memory. Just like doing something over again, such as playing a part of a song on an instrument, will help you remember how to play it and eventually you might even be able to play it without needing the music. Another way to improve memory is by relating information to something that you already know. It says that we have to exercise our memory in order to improve our memory.http://www.youtube.com/watch?v=grZuwo_YlY0
