Teeth whitening, Fatty livers, Fur farming

Available for over a year

Who should administer teeth whitening treatments? We look at who's qualified and who isn't. Also, why we are lagging behind our European neighbours in tackling fatty liver disease. We go to a fur farm in Lithuania to see how the industry is changing. And can gadgets check your mood swings - and help to cheer you up? PRESENTER: WINIFRED ROBINSON PRODUCER: PETE WILSON.
