Answer:
Everyone has me, but nobody can lose me. What am I?
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.
A thousand wheels, but move I do not. Call me what I am, call me a lot. What am I?
I am ten little beans your look at everyday.
Sing me to a baby about to go to sleep.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
