Sitting down for brief periods can help us recover from stress or recuperate from exercise. But nowadays, our lifestyles make us sit much more than we move around. Are our bodies built for such a sedentary existence?

There’s a factory inside you that weighs about 1.4 kilograms and runs for 24 hours a day. It’s your liver: the heaviest organ in your body, which simultaneously acts as a storehouse, a manufacturing hub, and a processing plant.

As his name suggests, rapper and documentary maker Professor Green has a past relationship with cannabis. Before finding success as a musician he sold weed, and between the ages of 16 and 24 he smoked cannabis every day - but things have changed since then. With those days behind him, Professor Green, aka Stephen Manderson, embarks on a uniquely personal film to take an in-depth look at our relationship with Britain’s most popular illegal drug and explores the arguments for and against legalisation. Stephen explores today’s booming UK cannabis industry, from the realities of life as a dealer, grower and even weed robber, to the consumers with ever-increasing options about how and what they buy. With cannabis laws around the world now changing – as US States like California fully legalise the drug – Stephen meets those hoping to make their future millions out of legalisation here in the UK. As he comes to reflect on his background and wrestle with his own past, Stephen explores addiction and the links between cannabis use and mental health.

COVID-19 is far from the first pandemic to wreak havoc in the world. A long line of infectious diseases have devastated and in some cases destroyed entire societies. Almost all of them started in animals and made the jump to humans. We are terrified of pandemics. And with good reason. Infectious diseases have cost the lives of countless people over the centuries, devastating families, towns, and even societies. The Black Death spread across Europe and Asia in the 14th century leaving millions dead in its wake. Between the 15th and 18th centuries, European colonists brought smallpox to the Americas, the Pacific region and to Australia. In Europe, the 17th century saw a series of major epidemics. And at the end of the First World War, more people died of the Spanish flu than on the battlefield. This documentary examines the causes of these epidemics - whether it be lack of hygiene, interaction with animals, overcrowding, or the growth of cities - and how people travelling helped to spread disease and promote pandemics. It also sheds a light on the impact these infectious diseases have had on politics and societal change. Today, the world is facing COVID-19. Measures such as quarantine and lockdowns are being rolled out in an effort to control the spread of the virus; and, just as our ancestors did before us, some are questioning how effective they are. Over the centuries, scientists managed to develop treatments and medicines to help control or even eradicate infectious diseases. Virologists are facing that task again with the coronavirus, as the world frantically searches for ways to overcome a pandemic which threatens our modern way of life.
