The brain is truly fascinating for its complexity and capabilities. Although there is still much to discover, I have always been excited to know that we have the ability to learn and improve more and more through mental exercises and continuous learning. Of course, despite how much we try to improve, it is very difficult to develop potentials much higher than the average in which our IQ is located. On the other hand, defining what a normal life is can vary according to the observer's perspective, since what may seem normal to some, is not necessarily so to others.
