The human brain is complex. What is also complex is the definition of “memory.” Simply put, memory is defined as the retention and recollection of certain people, times and events. It could be something as simple as a childhood experience. Or it could be more complex like the recollection and sensations of different thoughts and feelings. Every person has their own way of handling their memories.
What happens though, when the memories begin to fade? This will happen to all of us at some point in our lives. It will also affect each of us differently. Some of us will lose certain memories very slowly. Some of us will lose our recollections very fast. Some of us will be able to get those thoughts and feelings back after a while, while some of us will lose these things for good.
In your twenties, the brain cells start to gradually die off, and your body produces lower amounts of the chemicals needed for memory function. The memories will still be locked inside.
