// on a serious note: if they can transplant a head then why can't they transplant a spinal column and give paralyzed people the chance to walk again? //
It's a good question. The whole point about a spinal cord is that you can't just join it back up - if it's severed, you're paralyzed from the injury downwards, so how do they propose to address that with a body transplant. This has to be a belated April fools thing surely.
So they can transplant a face and they're suggesting they might be able to transplant a head...but...they can't treat nerve damage in conditions such as Bell's Palsy.
