The Kooks - Time Above the Earth lyrics

I've spent so much time above the earth
Thinking about life and each man's worth
How could one person be worth more than
A thousand people knocking on his door?
Still, the motion of your hair
Well, that could take me anywhere
Because you're happier than I
Please don't say goodbye

Then I get off the plane
A thousand thoughts reaching through my brain
Like, am I really here at all?
Will I see her again?
If I do, will it feel the same?
And am I really here at all?
