This just made me think of that great concert video I shared with you of The Flaming Lips and their song Do You Realize:

One, two, three, four
Do you realize
That you have the most beautiful face?
Do you realize
We're floating in space?
Do you realize
That happiness makes you cry?
Do you realize
That everyone you know someday will die?
And instead of saying all of your goodbyes
Let them know you realize that life goes fast
It's hard to make the good things last
You realize the sun doesn't go down
It's just an illusion caused by the world spinning round
Do you realize?
Ah-ah-ah
Do you realize
That everyone you know someday will die?
And instead of saying all of your goodbyes
Let them know you realize that life goes fast
It's hard to make the good things last
You realize the sun doesn't go down
It's just an illusion caused by the world spinning round
Do you realize
That you have the most beautiful face?
Do you realize?
