1. Until I am measured,
I am not known.  
Yet how you miss me,
When I am flown.
What am I?
 
2. My life can be measured in hours;
I serve by being devoured.
Thin, I am quick; fat, I am slow.
Wind is my foe.
What am I?
 
3.  Whoever makes it, tells it not.
Whoever takes it, knows it not.
Whoever knows it, wants it not.
What is it.
