I am everywhere but cannot be seen, captured or held, only heard. What am I?

What gets beaten, and whipped, but never cries?

Sitting down you have it, Standing up you don't.

I hold two people together but touch only one. What am I?

I am a window, I am a lamp, I am clouded, I am shining, I am colored and set in white, I fill with water and overflow. I say much, but I have no words.

This is your stomach's way of letting you know you've neglected it.

Though it be cold, I wear no clothes, the frost and snow I never fear; I value neither shoes nor hose, And yet I wander far and near.

What animal has feet on the head?
