More or Less: Behind the Stats - Delta cases, blue tits and that one-in-two cancer claim

The Delta variant is behind the big increase in the number of new Covid 19 cases in the UK since April. We take a look at what impact vaccines have had on infections, hospitalisations and deaths.

Chris Packham told viewers on the BBC?s Springwatch that blue tits eat 35 billion caterpillars a year. We get him onto the programme to explain.

How much does Type 2 diabetes cost the NHS a year? While exploring a dubious claim we find out why its hard to work that out.

Is it true that on in two people will get cancer? We?ve looked at this statistic before but listeners keep spotting it on TV.

We also ask: if the SarsCov2 RNA is 96% similar to the RNA of a virus found in bats - is that similar, or not?

Start the Week - Jackie Kay on Bessie Smith

Scotland’s former National Poet Jackie Kay celebrates the tempestuous life of the great blues singer, Bessie Smith. Born in Tennessee in 1894 Bessie was a street singer before she made it big at a time of racial violence and segregation. Jackie Kay remembers growing up as a young black girl in Glasgow and she tells Kirsty Wark how she idolised this iconic singer.

In Time’s Witness the historian Rosemary Hill explores the historical shift in focus from the grand sweeping narratives of kings and statesmen to a new interest in the lives of ordinary people. She argues that the turn of the 19th century and the age of the Romantics ushered in a more vibrant and serious debate about the importance of oral history, clothes, music, food and art.

The artist Michael Armitage is exhibiting his latest work at the Royal Academy in London until September. Born in Kenya in 1984 but based between Nairobi and London, Armitage is influenced by contemporary East African art and politics, as well as drawing on European art history from Titian to Gauguin. His exhibition Paradise Edict showcases 15 of his large scale works painted on lubugo bark cloth, a material traditionally made in Uganda.

More or Less: Behind the Stats - Covid deaths, outdoor swimming and care homes

The official number of deaths attributed to Covid 19 around the world in the whole of 2020 is 1.88 million. The global toll this year surpassed this figure on 11th of June. We look at how things are worse worldwide, despite vaccines and lock downs.

Does the UK have the worst bathing sites in Europe? That?s certainly a claim made by a number of newspapers. We show why this is not the case.

Health Secretary Matt Hancock has been in the news again with comments regarding care homes during the pandemic. Just how good was the government?s ?ring of protection? around care homes during the first wave - and the second? We speak to Steven Johnson about his book ?Extra Life: A Short History of Living Longer.?

Start the Week - London – villain and victim?

Love it or hate it, London dominates the UK politically, economically and culturally. It’s nearly 200 years since one critic famously described the capital as ‘the Great Wen’ a monstrous cyst sucking the life blood from the rest of the country. And for many that belief still stands. In The London Problem: What Britain Gets Wrong About Its Capital City the academic, and Londoner, Jack Brown untangles the complex strands of anti-London rhetoric, separating hyperbole from fact.

In 2019 the former special advisor Dominic Cummings told journalists to ‘get out of London. Go and talk to people who are not rich Remainers’, feeding into another perception of the capital. But the city is far from homogenous: 40% of Londoners voted for Brexit, and the population is the most ethnically and religiously diverse and has the greatest levels of poverty, compared to the rest of the country. The writer Jennifer Kavanagh spent two years getting out and talking to people on the streets of London – from beggars, to stall owners, to entertainers to thieves. Let Me Take You By The Hand tells the stories in their own words, of those who work and live in the capital.

The German composer George Frideric Handel moved to London in 1712 and made it his home. The countertenor Iestyn Davies celebrates Handel’s life in the capital, following his footsteps from his operatic triumphs in Covent Garden, past his local church in Hanover Square, to his Mayfair home. In Handel’s London Altos, at King’s Place on 24th June, Davies will perform a series of pieces showcasing his best work.

More or Less: Behind the Stats - The doubling of life-expectancy

Steven Johnson, author of Extra Life, tells the fascinating history of life expectancy, and the extraordinary achievements of the last century, in which it has practically doubled.

It?s a story that has data at its heart, from the ground-breaking invention of the category itself in 17th century London to the pioneering social health surveys of W.E.B. Du Bois in 1890s Philadelphia.

Tim Harford spoke to Steven about the numbers beneath possibly the most important number of all.

Start the Week - Lionel Shriver on life and death decisions

In a year when Covid-19 has had a devastating effect on families, with loved ones dying sometimes alone in hospital or without the usual funeral rites, Tom Sutcliffe and guests discuss mortality and what it means to have ‘a good death’.

In her latest book, Should We Stay Or Should We Go, the writer Lionel Shriver explores a number of alternative endings. The couple at the centre of her novel make a pact to end their lives when they hit 80, to avoid a slow decline either physically or mentally. As Shriver looks at how that decision might play out in reality, she’s arguing for a more open discussion about the end of life.

It’s a view shared by the consultant geriatrician David Jarrett. In 33 Meditations on Death – Notes from the Wrong End of Medicine he draws on family stories and case histories from his three decades treating those who become old and frail. Jarret’s book is an impassioned plea for everyone – old and young – to engage and make plans for the end.

The playwright Jack Thorne is part of the collaborative team (with designer Bunny Christie and director Jeremy Herrin) behind the National Theatre’s new play, After Life, based on Hirokazu Kore-eda's award-winning film. It follows a group of strangers as they grapple with the question: if you could spend eternity with just one precious memory, what would it be? Although all the characters are deceased, the play is a celebration of life, and about what matters to us most.
