Body Cells and Transformations

Something short and sweet for today:

On my ride home, I just recalled that someone said that "our body cells have an average lifespan of about 7 years, which means that who you are now is totally different from who you were 7 years ago". (Was it the principal who said that?)

Then I reflected on myself now, and myself 6 years ago (in Primary School, for simpler reference) . Take a analogy from computers: Not only has the hardware changed (totally) the software (i.e. operating system) has also been transformed. Likewise I have changed physically as well as mentally (how my system of thinking runs inside). Old ways of thinking have been replaced by new methods ...

And the list goes on but I need to sleep so good night! :D I'll continue this tomorrow if possible ... But does anyone read this blog??? Please tag if you come by here! Thanks!
