Riddles

1. Alive without breath, as cold as death.
Never thirsty, ever drinking.
All in mail, never clinking.


2. This thing all things devour,
Birds beasts trees flowers.
Slays king, ruins town,
Beats high mountain down.


3. Poor people have it,
Rich people want it,
And if you eat it you die.


4. I'm as light as a feather,
yet the strongest man can't hold me for long.


5. Try name three days in a row without using,
Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday.
