Michael Mosley and James Wong explore the effect that our food has on our most important and, in terms of energy consumption, our greediest organ. It influences our diet by generating cravings for foods such as fat - the most energy-rich food of them all. James heads off to Peru to reveal the surprising link that fat-rich, indulgent chocolate has with breast milk. Sometimes these cravings almost become an addiction - like coffee for example. So we visit a remarkable lab where a team is studying the effect of caffeine on bees and how that may help explain the hold that caffeinated drinks have over us. Together, Michael and James take on some of the hottest chillies on the planet to show what the burn does to our brains. Using the latest imaging techniques and incredibly detailed specialist photography, this is a whole new way of thinking about our relationship with food and the powerful effect it has on our minds.

November 22, 1963. The entire world is in shock. President Kennedy has just been assassinated during a trip to Dallas. Even Khrushchev himself seems touched by the tragic news. In a surprising coincidence, South Vietnamese president Diem was assassinated twenty days earlier, in a coup organized by his generals... The players are changing, but the Vietnam war drags on. America's new President Johnson sinks his country further into the quagmire of war. Close to three million young Americans discover Hell - the jungle, the unbearable heat, and the Viet Cong, with its tunnels and traps. For the first time, television plays a special role in the war. In 1968, the images of the terrible "Tet Offensive" revealed to the population the fiasco which took place in Vietnam: the massacres, the abuses of American soldiers and the obvious rout of their army. Soon the United States has no choice but to recall its troops; a victory for the communist world... But the USSR emerges from it ruined. Weakened by its various campaigns around the world, it will not experience the same success in Afghanistan. Soon, the "satellite" republics will resume their rights, overthrowing in turn the regimes imposed by Moscow. In 1989, the Berlin Wall fell and the Soviet Empire collapses... The red flag with the gold star dismounted from the roofs of the Kremlin. This is the end of the cold war. The war of the worlds ends.
