Lithium Sunset

Lithium Sunset, originally uploaded by Leo el Feo.

Sting has a song named Lithium Sunset. He got the title from the belief of Native Americans that sunsets cure depression. That staring at the sunset or being in it's light ( and sunrise also ) created a similar effect in the brain as that created by lithium. I love the song, it's on his Mercury Falling album.
I don't know about the story, but it sure feels good to be bathed by the sun.
