The surgery requires a staff of 150 doctors and nurses and exclusive use of a state-of-the-art operating theatre. The doctor clearly can't afford to go testing on animals.
That makes no sense. Do you know anything about animal or human research, and the ethics involved? I mean, history and accepted practices, not your personal beliefs. Because it looks like you're making things up to fit your preconceptions.
I gave links to people who did research with monkey head transplants, and reattaching rodent heads to the same body. I give links to the Declaration of Helsinki which rejects your stated belief.
And all you do is repeat yourself. It's getting boring.
