everyday our brain processes information. we take in information from our senses and make observations based off of what we pay attention to. Using our observations we can make perceptions using deductive reasoning or just prior knowledge. These perceptions then turn into our short term memory to know for a small amount of time and then forget later. Very few information or thoughts go to our long term memory. Things only go into our long term memory based off of how important it is to us like when we have a baby. The memories can fade of change overtime but you will always remember it.
