Some doctors think head transplants could soon be a real possibility. But there are many others who say they are a very bad idea.

A surgeonSomebody who carries out operations on unwell people. , Sergio Canavero, says it will soon be possible to take the head from a sick person's body and attach it to the body of someone else. He has already carried out transplantsWhen a part of one individual's body is given to another in surgery. on dogs, monkeys and dead human bodies.

Many think these operations are simply unethicalNot morally right. . In many countries, they would not be allowed to take place. But Canavero has carried on with his experimentsTests carried out, often by scientists, to find out whether an idea is true. in ChinaA country in East Asia, home to 1.4 billion people., which has less strictHarsh and believing that rules must be followed exactly. standards.

The idea raises many questions. One is whether the operation could really work on humans. It involves cutting the spinal cordThe bundle of nerves enclosed in the spine, connecting parts of the body to the brain. , but today there is no way to connect them back up. So the patientSomebody being treated by a doctor. would not be able to move their new body.

Even if the operation worked, the patient might face a crisis about who they really are.

But are they really a good idea?

Yes! The possible problems are worth it to give someone a new chance at life. It would be amazing if a young person with terrible disabilities could have a new body.

No! It would probably only be the rich and powerful who would be able to have head transplants. If they could keep getting younger and younger bodies, they could rule over the world forever.
