I was reading up this particular paradox the other day. It said that in every seven years, every cell of the human body gets replaced by a new one. The question is, if each and every cell in our body is changed to new in a lap of seven years and we physically become a new person then how can we say that we are still ourselves? How can we call us by our birth names, when in fact that body no longer exists.
I hate it when people change and specially when the new version of that person is so different that its impossible to even recognize them. I'm not talking about physical changes but instead changes which involve things like attitude and innocence. Its horrible to see how time, life and people bruise a person so bad, break their heart into million little shards and build a monster out of someone who was like an angel. But the worst part is that you were right there watching them change and go dark in front of your eyes, and you couldn't do a thing about it.
