Pound for Pound Lyrics

I know my body's not a perfect machine
I don't know how it keeps on working with me
'Cause if I'm going out I'm back after sunrise
If I'm going out I'm back after sunrise
If I'm going out I'm back after sunrise

I know my body's not a perfect machine
I'm just surprised that it endures this routine
'Cause if I'm going out I'm back after sunrise
If I'm going out I'm back after sunrise
If I'm going out I'm back after sunrise

I guess excessive is what you'd call it
The more I'm getting the more I want it
I shouldn't let this become a problem
But when I'm dead I suppose I'll stop it
But until then I want more

If I'm going out I'm back after sunrise
