An ambitious account of the story of human physiology in a feature-length dramatised documentary. Harnessing the magic of the most modern visual effects, we tell the story of the human body—inside and out—as it lives, grows, and dies on this predestined journey we call life. This unique National Geographic docudrama traces the life of a man, Adam, from the Cradle to the Grave, explaining the science behind our highs and lows, the rites of passage we all go through and exploring the inner workings of our bodies and how they change through time. The 90-year-old narrator, Adam, reflects on his life from conception through boyhood, adolescence and beyond, revealing the events that shape him. Along the way we meet the class bully, Adam's first love and the sergeant major preparing him and fellow recruits for Vietnam. With the aid of stunning computer-generated visuals, we go under the skin to reveal how Adam's body responds to major life events, and his story is told in dramatic scenes from the 1950s to the present day.
In recent years, researchers have started to understand why people love the foods they do, and that there may be a way to make snacks taste sweeter without adding any extra sugar – and it's all down to a trick that happens in the brain. This film meets a scientist who has grown a tomato that is sweeter and juicier than anything likely to be found on a supermarket shelf, and follows those hoping to become elite, professional tasters.
In recent years, close study of the aging process has opened up new ways that could help us all live healthier for longer. Can we move beyond treating individual diseases, and instead treat the aging process itself? But would a longer life necessarily be a better life? A loose-knit group of researchers believe the real breakthrough is extending our health span - the period of life spent free of disease.
In the early days of the space race, agency researchers in Russia and at NASA really weren't sure all what would happen to an astronaut in space. They didn't know if a human mind could handle actually seeing Earth or what would happen to the human body when exposed to long periods of weightlessness. Would their blood forget which way to pump? Would their eyeballs shift or their inner ears wig out? They sent up mice and monkeys and dogs, to see what happened, and in 1961, the Russians strapped a man to a rocket headed for orbit. Yuri Gagarin was the first person in space. The ultimate human guinea pig, he survived, becoming an international hero.
