You can win me and lose me but never buy me
You can not eat me and never want to part with me
I can make you cry or bring you joy
I am not a machine and definitely not a toy
You keep me but i am not forever just yours
You might find me in a case or on a shelf next to a vase

If your lucky and fight hard I might be yours

You measure my life in hours
I serve you by expiring
I vanish faster when I am thin
