Something worth adding is that there isn't anything in your brain that is immutable. We aren't really capable of observing some changes as they happen so gradually, yet it is quite obvious the changes have occurred. The way you perceive the world is going to be significantly different today than it was when you were an adolescent, yet you can't recall exactly what it was like to be that adolescent since you would have had to create an exact copy of your brain/body at that point in your life to have access the same context.
I always try to remember this fact when dealing with others. Past experiences and environmental context (that is to say, internal environment, e.g. blood sugar levels, hormone levels, neurotransmitter levels, etc) are extremely important to how you experience life on a day to day basis. It is literally impossible to fully imagine what someone else's experience is like, so it is important to listen carefully and be empathetic with others.
