Bionic limb is "mind-boggling" says Gloucester motorcyclist
Alex Paterson has a bionic arm.
He lost the limb in a motorbike crash nearly 40 years ago so the 58-year-old, from Gloucester, has had a rare medical procedure called Trans Muscle Reinnervation.
He says it is "mind-boggling" that he is able to control the prosthetic limb using his mind.
