Answer:
No legs have I to dance, no lungs have I to breathe. No life have I to live or die, and yet I do all three. What am I?
Every night I'm told what to do and each morning I do what I'm told. But I still don't escape your scold
I go through a door but never go in, and never come out. What am I?
I have feet on my head
I fly when I'm on and float coming off.
No matter how little or how much you use me, you change me every month.
