Everyone who casts a shadow

Everyone who casts a shadow seem to stand in the sun
And when your step leaves a track you seem to be going on

I know myself... I know my shades... but I don´t see no light
And if there's a track, it means no turning back
No matter what you try

Everyone who feels his heartbeat seems to be still alive
And by a look into your eyes I seem to know if you're lying

But from time to time there is more to life than just a muscle working deep inside
And to find the truth it needs much more than just a look into an eye
