80 years since Auschwitz-Birkenau was liberated, 87-year-old Holocaust survivor John Hajdu MBE shared his story of survival with the Princess of Wales this week and got a big hug. 

So, we’re re-running our episode where John tells Helen about his harrowing life as a young boy in Budapest seeing Jews persecuted & killed and his parents forced to labour camps. Comforted by his teddy bear as the horrors unfolded, the bear remains his constant companion.

John was honoured to be photographed by Rankin two years ago. Rankin said: “John’s bear is a tangible reminder that the stories we are telling happened in recent history and we must learn from these events – for a better future.”

Award-winning artist George Butler creates ink and watercolour drawings in situ in war zones, refugee camps and disaster areas all over the world and some of his work can be found in museum archives, including at the V&A.

His testimonies of ordinary people capture suffering, courage, moments of hope, and introduce us to real characters behind the headlines, whose situations we rarely hear about on the news. 

George has drawn in a leprosy clinic in Nepal; spent time with The Hazda tribe in Tanzania as they work with the honeyguide birds, and most recently been in Syria where Action Syria UK - a charity he co-founded - funds doctors and teachers.

His new book – Ukraine : Remember Also Me – is described by BBC's Chief International Correspondent Lyse Doucet as “a remarkable first draft of history – raw and revelatory”.

Jesse Dufton was the first blind person to lead a climb of The Old Man of Hoy – a daunting sea stack in the Orkney Islands, off the coast of Scotland. It earned him a Guinness world record and was the subject of Alastair Lee’s multi-award-winning documentary Climbing Blind. 

In newly-released Climbing Blind II, Jesse describes being “right at his limit” and “redlining for what felt like an eternity” as he leads a brutal and painful ascent of Devils Tower in Wyoming with his sight guide, wife Molly. 

Jesse has been climbing from the age of two, has many first to his name, and refuses to give in to a genetic condition which totally robbed him of his sight in his mid 20s.

Pioneering jockey Khadijah Mellah, from Peckham, became the first UK jockey to compete in a horse race in Britain wearing a hijab. 

A minute later, she made history again by riding her mount, Haverland, to victory in the Magnolia Cup at Goodwood. A film was made of her remarkable story and an academy set up in her name to help other youngsters from under-represented urban areas pursue a career in racing.

24-year-old Khadijah explains how, as a young Muslim woman, she’s changing perceptions in sport. She recently chatted to the King and Queen, who she's met a number of times, and took part in the Hillclimb at Goodwood’s Festival of Speed in an Aston Martin Valkryie with F3 legend Peter Dunbrek.

Laura Harnett spent 20 years as a high-flying corporate executive, in the boardroom at Selfridges and working for brands like IKEA and Coca-Cola. Never did she imagine she’d be championing a humble cleaning sponge.

However, frustrated by supermarket aisles full of microplastic-filled cleaning tools, and a devastating diagnosis of breast cancer, she gave it all up to become an entrepreneur in her 40s and start Seep.

Seep is a B Corp which designs eco-friendly, plastic-free, biodegradable cleaning accessories using natural renewables like wood, loofah and bamboo, and aims to stop a billion plastic cleaning tools going to landfill by 2030.

Michelle Feeney founded Floral Street Fragrances – an award-winning British brand with sustainability at its core – after a dynamic career leading top global beauty names, including Estee Lauder and Mac Cosmetics.

The inspiration to create clean, affordable fragrances which won’t impact the planet, came during what Michelle describes as her gap year, aged 51. Inspired by flowers and vibrant culture, Floral Street has collaborated with the Van Gogh Museum and watch this space for another exciting partnership. 

As Black Friday approaches, Michelle explains what Floral Street is doing to help, partnering with Clean Hub, given the sales frenzy generates 25% more waste – an excess of 100 million tonnes.

Seasoned barrister & environmentalist James Cameron - one of the leading architects of COP – reflects on three decades of arguing for a fairer and more sustainable planet.

He co-hosts a new podcast series – Fossil vs Future – with his 30-year-old god-daughter Daisy Nicholls who works in sustainable finance. It’s a refreshing, authentic conversation exploring the climate crisis through different generational lenses.

Together they discuss a series of what they call ‘what abouts’ – what about the ocean, food, China, international law, nature-based solutions, the role of finance and much more.

Helen takes an 11-degree chilly dip in Windermere in the Lake District with renowned Cold Water Swim Coach Gilly McArthur to experience the benefits of cold exposure and blue spaces.

Gilly explains the compelling science behind how the cold improves our physical and mental wellbeing, what it does to our brains and bodies, and how nature and ice-swimming has helped her through some painful times.
