You Are No Longer Who You Were 10 Years Ago

You, who was present 10 years ago, were not the current you. That’s a fact. How so? Most of what you are made up of – cells — have all but disappeared. They have turned over. This video gives a nice impression of this phenomenon.

So what happens with your body over time? Well, the body goes through a regular wear and tear at the cellular level; your molecular equipment gets corroded after working a while. In several instances, there is a pile up of dysfunctional substance accumulating in the cells. Thus, there is a constant need to get rid of the old and make new proteins, cell and tissues.

Hence the above statement that you are not the person from 10 years ago, most of the ‘stuff of life’ in the body has been replaced. This revelation often makes people uncomfortable, and invariably the next question they ask is whether the part of their body that contributes most to their individuality, their brain, also changes? The answer is a source of a fleeting period of relief.

Relief because most of your brain cells do not turn over by the time you reach adulthood. However, this relief is for a fleeting time period since the subsequent facts make ‘your current self’ appear even more temporary. The actual connections between these cells, the dendrites and axons, are one of the most plastic (as in malleable) parts of the body.

So although your neurons don’t die, they are in a perpetual state of change. And with each change, ‘you’ change.
