Answer:
I can be thin but not fat; in your body but never on your placemat. I'm always better when I'm fresh but you'll never see me in the flesh.
I belong to everyone. Sometimes make you happy, sometimes make you sad. I will never end until the day you do. What am I?
Only one color, but not one size, stuck at the bottom, yet easily flies. Present in sun, but not in rain, doing no harm, and feeling no pain. What am I?
If you drop me, I'm sure to crack. Give me a smile and I'll always smile back. What am I?
I cannot be other than what I am, until the man who made me dies. Power and glory will fall to me, only when he last closes his eyes.
Almost everyone needs it, asks for it, gives it. But almost nobody takes it.
