Refrigeration and Air Conditioning

Hamlet: The air bites shrewdly; it is very cold.
Horatio: It is a nipping and an eager air.

My highway is unfeatured air,
My consorts are the sleepless stars,
And men my giant arms upbear—
My arms unstained and free from scars.

If we cannot end now our differences, at least we can make the world safe for diversity. For, in the final analysis, our most basic common link is that we all inhabit this small planet. We all breathe the same air. We all cherish our children's future. And we are all mortal.
