Look Around You: 2x2

Health

The team looks at advances in healthcare, and Jack Morgan goes under the knife as Dr Fu supervizes the efforts of a robot-surgeon called Medibot to create the perfect face. Other presenters try out a new toothbrush that burns away plaque – though with one rather serious side effect… And in a special report, the team visits a Sleep Institute and meets its director, Professor Craven, a man with some cutting-edge ideas.
