as free as a child

I envy the children...
They can do whatever they want.

They don't worry about the next hour, the next day, only older people worry.

When I was still small, I love to ride on a swing.

I love to kick the dust and let my swing fly, and fly, and fly...
I love the wind against my face, my hair, adrenaline pumping in my veins...

I never worried about other people, I worried more with what I want -- junk food to eat.

Why do people worry more as they age?
I don't even want to hear about the word "worry" sometimes. Let worry worry about itself...
We have our own lives to live and life is too short to worry.
