Answer:
Without me everyone would lose their head. What am I?
I am put on the table, cut, but never eaten. What am I?
I am like thunder in your cranium
Iām hard as a rock and as light as a feather. Iām passed on to one another. Poor people need me and rich people have me.
I am a busy worker who is a water mammal.
No matter how little or how much you use me, you change me every month.
