The Polygamist: How the Netflix show is starting conversations in South Africa

There’s a new Netflix show that has got lots of us talking: The Polygamist. It’s a drama based in South Africa about a wealthy businessman named Jonasi Gomora who has multiple wives and a mistress. It’s packed with betrayal, revenge… and cheating. It’s become the most-watched Netflix show in South Africa and Kenya, and it’s hit the top 10 in countries like Nigeria and Romania too. But it’s also got people talking about polygamous relationships - which are legal in South Africa and many other countries - and whether they work.BBC reporter Khanyisile Ngcobo joins us from Johannesburg to unpick how people in South Africa have been reacting to the show, how polygamy traditionally works, and how conversations around it are changing. And we hear from fans in Ghana, South Africa, the US and the UK, who share what their group chats have been saying about the hit show.Instagram: @bbcwhatintheworld Email: whatintheworld@bbc.co.uk WhatsApp: +44 330 12 33 22 6 Presenter: Hannah Gelbart Producers: William Lee Adams and Chelsea Coates Editor: Verity Wilde

Should you wear earplugs to concerts?

According to the National Institute of Health, long or repeated exposure to sounds at or above 85 dBA can cause hearing loss. The noise levels at a big concert or live music gig typically fall between 90 and 120 dBA, according to the British Academy of Audiology. These levels depend on things like the type of music, whether the venue is indoors or outdoors, and how close you stand to the speakers. So what impact is this level of noise having on our ears and can the trendy, visible earplugs that are booming online protect you from hearing loss. We speak to Andrew Rogers from BBC Newsbeat who has been reporting from gigs and festivals across the UK and speaking to earplug users.BBC Health Correspondent, James Gallagher gives us a full explanation on what happens inside our ears when we are in loud environments.Instagram: @bbcwhatintheworld Email: whatintheworld@bbc.co.uk WhatsApp: +44 330 12 33 22 6 Presenter: Hannah Gelbart Producers: Lucy Davies, Benita Barden,Eleanor Sly and Liv Cleal Editor: Verity Wilde
