What in the World: How have older reality tv shows aged?

Precipitous mountain roads, specially-modified bikes, and deadly consequences. Simon Maybin spends time with the young men who race down the steep roads of Colombia’s second city Medellin. Marlon is 16 and he’s a gravitoso - a gravity biker. He hooks onto the back of lorries or buses climbing the precipitous roads to reach high points around the city. Then, he lets gravity do its thing and - without any safety gear - hurtles back down the roads, trying to dodge the traffic. This year, two of his friends have died gravity biking and Marlon has had a near-fatal accident. But he’s not quitting. So what drives young men like him to take their lives into their own hands? And what’s being done to stop more deaths? Presenter/producer: Simon Maybin (Image: Marlon with his bike ready to ride back down into Medellín. Credit: Simon Maybin/BBC)

Marawi in the southern Philippines is a ghost town. In 2017, it was taken under siege for five months by supporters of Islamic State who wanted to establish a caliphate in the predominantly Muslim city. After a fierce and prolonged battle, the Philippine army regained control – but Marawi was left in ruins. Two years on, reconstruction has barely begun and over 100,000 people are yet to return home. Philippines correspondent Howard Johnson tells the story of Marawi from the siege to the present day, through the eyes of two of its residents: a Muslim who risked his life to save his community and a Catholic priest who was held hostage by extremists.Producer: Josephine Casserly(Photo: Marawi's Grand Mosque pockmarked by bullet holes and small artillery fire - in the area that the authorities call the Most Affected Area (MAA) or Ground Zero of the siege of Marawi.
