Do you know someone who would lose their head if it wasn’t screwed on? We have a doctor who can fix that – or at least he says he know how to fix it. Neurosurgeon Sergio Canavero has published a new paper outlining how he can conduct whole brain transplants by simply attaching a head to a new body. If this sounds vaguely familiar, Canavero was in the news quite a bit around 2017 when he first proposed this idea – it is not new but he claimed he had new technology that made it feasible. He dropped hints that he had some volunteers. When he could find a country to allow this surgery, he switched to promising he would transplant frozen brains in 2020. Needless to say, that didn’t happen either. Now Dr. Canavero is back again – claiming he has proof that head transplants work but he’s sticking to rain transplants because it’s better for old brains to be installed in young heads. Does this sound like Canavero is changing his focus to people who want to live forever?
