Why we do what we do?

Why are we eating too much
even we know quite well, it is not good?
I always make a fuss.
There must be something in our food.

Why don’t we regularly exercise?
Don’t we know that it is good for our health?
I just don’t know why.
I can’t really answer it myself.

Most people want to be rich.
Yet they keep spending their money.
‘You have to save money’ that’s what they teach their kids.
You see, it is really funny.

There must be something,
that try to stop us to be the best.
I am just wondering,
can you help me solve this case?

I am busy and really don’t have time.
You see what I am getting to.
Yet I am still writing this rhyme.
So I don’t know why I do what I do.
