Tool head

The units created for good or for worse
Sometimes a blessing the second and first
Allways a struggle that wasn't a thought
But now it's blaring, a fight to be fought
The beauty's amazing when viewing the view
The old is forgotten when living the new
Leaving's a notion that never does die
But the bars are embedded ending the lie
life is a moment, and living's a choice
the head is a tool but not the one voice
