You gotta be crazy, you gotta have a real need.
You gotta sleep on your toes, and when you're on the street,
You gotta be able to pick out the easy meat with your eyes closed.
And then moving in silently, down wind and out of sight,
You gotta strike when the moment is right without thinking.

Head transplant: man will be attached to new body in under an hour and aim is immortality, doctor says

And after a while, you can work on points for style.
Like the club tie, and the firm handshake,
A certain look in the eye and an easy smile.
You have to be trusted by the people that you lie to,
So that when they turn their backs on you,
You'll get the chance to put the knife in.

The first man set to undergo a head transplant has been revealed, saying that he finds the controversial surgery “very scary, but also very interesting”.
Valery Spiridinov is set to be the first person to undergo the operation. It will be carried out by controversial Italian doctor Sergio Canavero, whose optimistic plans have mostly been met with skepticism.

You gotta keep one eye looking over your shoulder.
You know it's going to get harder, and harder, and harder as you
get older.
And in the end you'll pack up and fly down south,
Hide your head in the sand,
Just another sad old man,
All alone and dying of cancer.

The procedure — which Canavero has admitted is just a first step towards his ultimate aim of creating immortality — will see a man's head removed and placed on a donor's body.
