Watch Look Around You Season 2 Episode 2 Online

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.
