A number of leading British doctors have joined forces to publish a book on their predictions for the future of medicine.
Their forecasts include microchips implanted in the body which take temperature, monitor blood pressure and tell us when to visit the doctor.
The doctors also predict progress in the treatment of paralysis, brain damage and debilitating conditions like Alzheimer's disease -- as well as fertility treatments which will allow every woman the chance to have a baby.
