In mid-2021 hot tub companies were king. Unprecedented demand through covid pushed up sales as people stayed at home. Some of Europe's well known suppliers boasted up to a 400% increase in sales compared to 2019. Companies simply could not get a hold on enough stock. In China on/off lockdowns caused a part shortage. Waiting lists across Europe went as far as six months. Some of the world's biggest tub producers made record profits.

Then in early 2022 an industry went from its heyday to doomsday in a matter of months. The reason: The cost of electricity. Across Europe, some owners are draining their pools as the cost of living crisis bites. One in five hot tub owners say they now never use them, while a further third said they hardly ever use them, according to a new major survey.

Business Daily's Rick Kelsey speaks to Chris Hayes from BISHTA, the trade association for hot tub installers in the UK and Ireland, about the type of people who can now afford a tub. We travel to Valencia in Spain to hear how health spas are affording to heat their water. Sophie Clarke, who’s selling her tub on a European forum tells us how upset she is to see it go and we hear from international hot tub supplier Christina Mantoura Clarke on how her business survived when so many competitors went bust.

Lab researchers work by this motto. But for Dr Natalie Kenny, founder of international lab testing and medical training firm BioGrad, it’s proved true in every aspect of life.

We hear from some of the many small-scale farmers in Kenya who are using apps like What’sApp, Facebook and Instagram to share information about the best way to grow fruit and veg and sell direct to consumers. From the vibrant markets of Nairobi to the lush green slopes of Mount Kenya Sam Fenwick investigates how farming entrepreneurs are using smartphones to grow profits as well as peas. But running a business online can be challenging in Kenya where internet connections can be patchy and data bundles expensive. Safe access to the internet is seen as development goal. At the 77th session of the United Nations General Assembly governments, the private sector, philanthropic funds and international organisations agreed that investment in digital infrastructure would help drive growth in emerging economies. US$295 million was committed to advance inclusive digital public infrastructure.

University sport in the US has become huge business. For decades, students' share of those earnings only came in the form of scholarships. As television contracts got bigger, so did the calls for change - and last year students were granted the right to earn off their name, image and likeness.

Hear from former SMU college football player and professional artist Ra’Sun Kazadi, Texas A&M University Athletic Director Ross Bjork, CEO of MSP Recovery John H Ruiz and Courtney Altemus of Team Altemus, part of the advance group of NIL advisers.

As many as 7 million Americans who could work, aren’t. These are people who have dropped out of the workforce - they have given up on finding a job or are simply not looking.

And similar trends can be seen in other wealthy countries. So what is going on?

Ed Butler speaks to Nicholas Eberstadt, a researcher at the American Enterprise Institute.

He’s recently updated a book which examines the extraordinary increase in men – and it is mainly men in the US - who’ve decided they don’t just want to quit their jobs, they want to leave the workplace for good. And it’s something that’s been going on since the 1960s.

Greensill Capital was a UK based finance firm and a darling of investors which made its money by lending to businesses. It went into administration in March 2021, leaving investors facing billions in losses.

And what does it teach us about the way modern entrepreneurs, like Australian-born Lex Greensill, try and promote themselves?

Ed Butler speaks to Duncan Mavin, a financial journalist who followed the downfall of Greensill – he’s written a book about what happened.

Laura also takes a tour of the station and finds out about its much-admired predecessor - the Pennsylvania Station of the early 20th Century.

The use of robots in North American workplaces has increased by 40% since the start of the pandemic and the small to medium sized businesses, which never automated before, are getting in on the act. The robotics industry has responded to the global increased demand by creating more and more customisable robots, which can be leased or hired.

Ivana Davidovic explores what effect this has had - and could have in the future - on the labour markets, innovation, but also on social inequality.

Ivana hears from a small restaurant owner from California who wouldn't be without her server robot Rosie any more, after months of being unable to fill vacancies. Joe Campbell from the Danish company Universal Robots and Tim Warrington from the British company Bots explain how they are taking advantage of the post-pandemic "great resignation" and which industries are next in line for a robotics boom.

Karen Eggleston from Stanford University explains her research into the consequences of the use of robots in over 800 nursing homes in Japan and Daron Acemoglu from MIT discusses whether robots in workplaces will liberate their human colleagues or simply entrench inequality.

Is space the final frontier for meat grown from animal stem cells?

Elizabeth Hotson asks whether growing steaks under micro gravity conditions could help in the quest for food security and whether, back on earth, consumers could be persuaded to stomach meat reared in labs.

We hear from Didier Toubia, the CEO of Aleph Farms who defends his space meat mission from accusations of gimmickry.

Seren Kel, the science and technology manager for the Europe region of the Good Food Institute, gives her view on the environmental impact of cell-gown meat and Dr Jason Michael Thomas, senior lecturer in psychology at Aston University explains how reluctant consumers might be persuaded to try new and strange-sounding foods.

When women's tennis world number one Ash Barty suddenly announced in March 2022 that she was retiring from tennis, it was huge shock.

Barty, a three time grand slam champion, was only 25.

At the time she said she was leaving professional tennis to pursue other life goals.

Quitting is often seen as a negative thing to do, but in this episode we explore the positive side.

PwC’s Global Workforce Hopes and Fears survey of more than 52,000 people in 44 countries showed that one in five workers planned to quit their jobs in 2022.

Marie Keyworth speaks to Moya Dodd, former vice-captain of Australia’s women’s football team - The Matildas. She now works as a lawyer in Sydney and says Barty's decision to 'quit at the top' could be a lesson to us all.

Career coach Sarah Weiler has quit several roles herself, and has now made it her job to help others – how do you know when it’s time to move on?

And Dina Denham Smith is an executive coach based in the San Francisco Bay area. She helps what she calls ‘high performing, high achieving’ people make decisions. She tells Marie how you can improve your situation if quitting isn’t an option.

Presented and produced by Marie Keyworth.
