It is said that the human body rebuilds itself every 7 years. Whether 7 years is an exact time, an approximation, or even a completely made up number is irrelevant. It is still fact that certain parts of the body change over time. The outer layer of our skin is changed daily, the water in our bodies is changed approximately every 96 hours, and our tissues alter their structures according to cell production. Even if none of this is true, one still knows that the body grows. Isn't growth still change? If one can prove that the physical aspects of our lives are changing, can the same be concluded about the mental aspects? It can be argued that the mind is the only thing that truly remains the same, or constant. I have read somewhere that the nerve cells in your brain last a lifetime and do not multiply. Does this alone disprove my whole argument?
The mind transcends the brain and does not limit itself the way the brain does. I believe that the mind grows the same way that the body does over time. Not in the literal sense, but through education, knowledge, and experience. As I look back on the years I mentioned earlier, I can say that in each stage of my life, both my body and mind were different. As a two year old, I was thin and small; I only spoke Polish, my mind was not aware of any other languages until more change occurred; and the most important things in my life were ice cream and cartoons. As a 6 year old, I was still thin, but taller; I spoke English, a language that still seemed foreign to my mind; and I'd help my mom take care of my newborn sister, a change in my life that I learned to love. As a 10 year old, I grew wider and taller; I resented the language I was born into as well as the mother I was born from for giving my sister more attention than she gave me. At 14, I began to resent myself. All of these physical and character traits were temporary. If these two elements have changed, what else is there to account for?
Some may disagree, but I believe I am made up of a body and a mind; the two are in constant flux whether or not I want them to be. I will continue to redefine myself until death. Tim O'Brien may believe that there is something else that makes him up, a soul perhaps, that is unchanging, that the essence of "Timmy" still remains, but I beg tot differ. I am no longer who I was in the beginning, and who knows who I'll be in the end.
