Two Halves

You want this now you want that
Well, when you're so young you wanna be older
I believe in a perfect world
Forty one, somethings start to fade
And when you're older you want the body you have now
Can't have it all, you should enjoy what you have
Twenty one, everything stays in place

It wasn't that long ago in the grand scheme of things

You rule your own universe
Well I know what you want, well I know what you want
Well I know what you want, you want the better of two halves
The only gun you'd ever need is in your hand
But I know what you want, well I know what you want
It wasn't that long ago, you think you're so much smarter now
The only gun you'd ever need will be in your brain
