Of all the wonders of the human body, there's one more mysterious than any other. Blood: five precious litres that keep us alive. Yet how much do we really know about this sticky red substance and its mysterious, life-giving force? Michael Mosley gives up a fifth of his own blood to perform six bold experiments". From starving it of oxygen to injecting it with snake venom, Michael reveals the extraordinary abilities of blood to adapt and keep us alive. Using specialist photography, the programme reveals the beauty in a single drop. Michael even discovers how it tastes when, in a television first, he prepares a black pudding with his own blood.

For centuries scientists have been attempting to come up with an elixir of youth. Now remarkable discoveries are suggesting that ageing is something flexible that can ultimately be manipulated. The scientists are attempting to piece together why we age and more vitally for all of us, what we can do to prevent it. But which theory will prevail? Does the real key to controlling how we age lie with a five-year-old boy with an extraordinary ageing disease or with a self-experimenting Harvard professor? Could one of these breakthroughs really see our lives extend past 120 years?

The film explores the growth of exponential technology and where it is taking us. It focuses on how future technology could significantly change the two inevitable features of the human experience; punching the clock and fading away. 'The Future of Work and Death' explores how advanced automation, AI and technological singularity could be achievable in the next 30 years.
How job obsolescence and technological unemployment could consequently occur and how digital immortality can occur may not be a thing of science fiction. But what are the socio-political repercussions of these innovations and are we ready for them? Does working less mean living more and is ending ageing incumbent on us? Worldwide experts in the fields of futurology, anthropology, neuroscience and philosophy share their thoughts on these future advancements.
