Dr Chris van Tulleken, Dr Hannah Fry and Michael Mosley examine the latest research and explore some of the big questions about Covid-19 and the pandemic it has created. Michael visits the UK government's high-security laboratory Porton Down, where vaccines are being tested. He also uncovers what the experience of the 2002 SARs epidemic reveals about this one. Both were caused by coronaviruses, but certain key changes to today's virus have allowed it to infect the world, where SARs was contained.
Michael Mosley has set himself a truly ambitious goal: he wants to live longer, stay younger and lose weight in the bargain. And he wants to make as few changes to his life as possible along the way. He discovers the powerful new science behind the ancient idea of fasting, and he thinks he's found a way of doing it that still allows him to enjoy his food. Michael tests out the science of fasting on himself - with life-changing results.
By the close of the Industrial Revolution, the American food supply was tainted with frauds, fakes and legions of new and untested chemicals, dangerously threatening the health of consumers.

Wiley embarked upon a series of bold and controversial trials on 12 human subjects who would become known as the “Poison Squad.” Following Wiley’s unusual experiments and tireless advocacy, the film charts the path of the forgotten man who laid the groundwork for U.S. consumer protection laws, and ultimately the creation of the FDA.
