1)
I'm the beginning of sorrow,
and the ending of sickness,
I'm the sun but never in the light.
What am I?
2)
What always runs but never walks,
often murmurs, never talks,

inside the white house there was a red house,
inside the red house there were lots of babies.
What is it?
4)
The one who makes it, sells it.
The one who buys it, never uses it.
The one that uses it never knows that he's using it.
What is it?
5) (one of my favourites~)
A cyclops stares from a blank white face,
Seven earrings his visage grace;
On his core are five tattoos,
Ebon black his pair of shoes.
On his back six scars dub deep.
But he neither cry nor weep,
His job: to tumble, bounce and fall,
But he's no fool, no not at all.
6)
You see a man walking down the street with a cart; the cart has a body in it.
You ask the man wheeling the cart who it is, and he replies:
"Brothers and sisters I have none,
this man's father is my father's son."
Who is the person in the cart?
7)
Be you ever so quick, with vision keen,
by your eyes, we are never seen.
Unless perchance it should come to pass,
you see our reflection in a looking glass.
What are we?
8)
What is the more you take, the more you leave behind?
9) (really hard one >.<)
A master asks his pupil:
"I am four times as old as you were when I was the same age as you are now.
I am forty years old. How old are you?"
10)
I'm not alive, but I grow;
