All about, but cannot be seen, Can be captured, cannot be held, No throat, but can be heard. Who am I?
I cost no money to use, or conscious effort to take part of. And as far as you can see, there is nothing to me. But without me, you are dead.
Until I am measured I am not known, Yet how you miss me when I have flown.
I have a face, yet no senses. But I don't really care, because time is of the essence.
