Channel 4 announces a documentary called 'The Great ADHD Myth?' Lots of people - many of them with ADHD - react angrily, arguing the show's title adds to the stigma and distrust around diagnosing the disorder. The documentary aims to explore the causes of ADHD - some people think that's a conversation we urgently need to have, given growing rates of diagnosis, lengthening waiting lists, and rising benefit claims related to the disorder. We find out how ADHD is defined and diagnosed, ask whether there is any evidence of over-diagnosis, and explore the disorder's history.

Some historians suggest the NHS would never have got off the ground without large numbers of overseas staff, but why was there such a reliance in the first place, and when did the backlash begin? Adam Fleming speaks to Andrew Seaton, history researcher at the University of Manchester and author of 'Our NHS: A History of Britain's Best Loved Institution'.

An NHS campaign group posts on social media to celebrate the organisation's overseas workers, but there's a backlash from people who think we should have more British-born doctors and nurses. Would the NHS collapse without these foreign workers? We find out how many are employed and ask whether there could ever be enough British-born staff to replace them. The NHS has long relied on foreign workers - we go back to the organisation's beginnings. Plus, where does the NHS fit into the UK's broader immigration row?

The idea of a North-South divide in England carries weight with many people, but is there any historical basis for it, and how far back does it go? Adam Fleming speaks to James Hawes, author of The Shortest History of England.

Andy Burnham's pledge to rebalance power in Britain shines new light on a long-standing divide stretching across England. Some say the new Prime Minister's focus on the north is long overdue, while others argue it's divisive and that the south has its problems too. So how deep does the divide go, and where does it come from? We explore the geology, geography and the history. People from north and south often sound different - we discuss the links between accents and prejudice. And we revisit a TV series that has been instrumental in the way the Prime Minister, and many others, view the north of England.

The alleged murder of Ann Widdecombe prompted a debate about how we should speak about the dead, after some people came under fire for comments they made in the wake of her passing. When is the right time to bring up criticism of a public figure that’s died, and how do you accurately reflect someone’s life and legacy? To find out, Adam Fleming spoke to Ann Wroe, obituaries editor at The Economist.

The suspected murder of Ann Widdecombe - and the reaction to it - prompts a debate about what we should and shouldn't say about someone when they die. The former politician was celebrated by some, but pilloried by others for her lifestyle and political views. So is it ever OK to speak ill of the dead and, if so, when and in what way? Plus, we explore the origins of the phrase itself, and speak to an obituary writer about which details to include, and which to leave out.

An online community of women, who are wary of men and their relationship motives, has come up with a check-list for finding the perfect partner. Adam Fleming speaks to Sarah Ditum, a journalist and author, about how ‘female dating strategy’ works in practice.

A contestant on Love Island prompts debate over her interactions with the men on the reality TV show. Some viewers suggest Jasmine has been "pink-pilled" - a reference to a mindset that sees women's relationships with men as adversarial, and is a reaction to the manosphere. Others think Jasmine shouldn't be vilified for some of the same traits displayed by men on the show, and in real life. We find out what pink pill content is, and where it came from. Plus, how does this mindset play out in real life? We explore female dating strategy.
