What Am I?

We grow past time.
We will be a different person in future compared to our youth.
Thus I am no exactly who I am.
We are changing and growing.
Every moment and every choice combines who we are right at the moment.

I maybe a combination of bones, fresh, blood, and skin.

I maybe a system that is composed of 60,000,000,000 cells.
And I was one of the cells which last about 30 minutes then died in the whole of me.
Also we replace every one of those cells in a 7 year cycle.

I may have a soul and a body. I can see my body, then what about the soul?
Is it my mind?
Is it my heart?
Is it divided into many pieces that makes me a freak?
There's nothing I can feel by my heart.
My heart is just an organ for supporting the blood for my body to keep me alive.

I maybe an accomplishment of the incorporation process of an egg and a sperm.
Am I the fastest sperm? I don't do much sports.
Then am I the most smart one? I keep being silly.
Oh, I'm the most criticised one. I always doubt and seek for evidence.

Am I the number on the bank statements?

Am I the mark of my transcripts?

Am I a link of the food chain?

Am I a driver of the society progress?

Am I the name and passport number?
Why you can defined me by such things?

I maybe one of the living people those want to change but can't obey the so called destiny.

What am I?

What is me?
