PS - I've got a dodgy knee - give it ten years and I bet they will be able to digitally X-Ray my knee, produce a perfect version in a computer before printing it out and replacing the existing one. The cool bit is it would be a perfect version of *my knee* so it would work as it did after rehabilitation! I'm not so scared of getting old know![]()
They will be using your own stem cells as the printing ink too!
