During an unguarded conversation between President Putin and President Jinping in Beijing, the Chinese leader suggested that scientific developments meant that by the end of the century people might live until 150.

So, what is it like to live to an old age and will 150 years ever be possible?

We bring together two women in Australia, Janet and Myfanwy, with a combined age of 202. One of them still drives. The other stopped getting behind the wheel at 96.

They say they both enjoy busy lives. Janet at 102 doesn’t relish the thought of being 150 though: “Think how doddery and staggery you would be.” And Mwfanwy adds: “I don’t want to live forever!”

In another conversation, 87-year-old Elaine in the United States has this advice: “We’ve all been through difficult times, we’ve all had terrible things happen to us, but you just get past it, and you put one foot in front of the other and you just keep on going.”

We also hear from three distinguished researchers who discuss the reality of living a long life and the science of anti-aging.

This edition is from BBC OS Conversations, where we bring people together to share their experiences.

The global fertility supplements industry has an estimated worth of over 2 billion dollars, and it’s growing. Some experts have raised the alarm around poor regulation of companies and the products they sell.

In this episode of BBC Trending we investigate Pink Stork and other supplement companies which say they can help you get pregnant. Now, they're being promoted heavily on social media and beyond. What is the science behind some of the claims?

And what does this say about regulation of the supplements industry as a whole?

Rodrigo Medellin loves bats. The Mexican conservationist has been obsessed with the often maligned creatures for over six decades. As a child, he kept blood in ice cube trays in his parents' freezer, to feed to his pet vampire bats. He went on to create Mexico City’s first ever bat festival, and to work with governments, universities, NGOs and researchers all over the world. To many, Rodrigo IS the "bat man."

Like many Mexicans, he is also fiercely proud of the country’s native spirits: tequila and mezcal. The agave spirits are hugely important for Mexico’s economy, especially in the states of Jalisco and Oaxaca. Exports of the drinks are worth billions. Tequila and mezcal have become increasingly popular in recent decades, with sales boosted by big budget celebrity-owned brands designed to appeal to the US consumer. From Kendall Jenner to George Clooney, US celebrities have been riding high on the mass market appeal of the liquor.

But the boom in these industries has had unintended consequences for Rodrigo's beloved bats. Often the agave the spirits are made from is harvested early, before the slow-growing plant can flower. This means bats cannot feed from the nectar, and critically, they can’t do their job as pollinators. This contributes to agave monocultures which are susceptible to disease and blight.

Rodrigo explains how he wanted to change the way the industry works, creating a “bat-friendly” certification for tequila and mezcal producers who leave 5% of the agave untouched, to bloom. But why have so few brands been certified, why is the programme controversial for some producers, and why are bats a tricky sell as far as conservation for many people and communities? Sarah Treanor spends time with Rodrigo in Mexico City and Oaxaca to find out.

How does a seemingly ordinary boy prove to be so extraordinary that he’s given a halo by the Catholic Church? Saint Carlo Acutis was just 15 years old when he died in 2006. William Crawley travels through Italy to the places most associated with the young Carlo to discover for himself what set this teenager apart from the rest.

In Assisi, William meets Carlo’s mother Antonia Salzano Acutis who reveals how her son showed an unusual generosity for a teenager. He visits Carlo’s tomb, where Domenico Sorrentino, Bishop of Assisi, explains the connection between St. Francis and Carlo, as a bridge from the past to the present.

But is it all too convenient for the Catholic Church in this Jubilee Year to find a saint that appeals to this younger generation? William ponders this in Rome with John Allen, editor of Crux, the online Catholic newspaper, before heading off to St Peter’s Square and the Dicastery for the Causes of Saints where Monsignor Alberto Royo explains the investigation into Carlo’s life to see if it was one of ‘heroic virtue’.

The history of Gaza dates back more than 5000 years. In antiquity, it was a key port on the Mediterranean coast. Assyrians, Ancient Greeks, Romans, Byzantines and the Ottomans have all left their mark on this small territory. This rich history is seen by Palestinians as central to their identity. Amid the death and destruction of the war, the BBC’s Middle East Correspondent Yolande Knell meets the Palestinians who’ve desperately tried to save what remains of Gaza’s past.

Over the past year, BBC Eye has documented life in Ukraine’s second largest city, Kharkiv, helping to capture the deeply personal stories of those living under the continuing shadow of war. Just 30 kilometres from the Russian border, this Russian-speaking city has sustained some of the heaviest attacks of the war.

Reporter Albina Kovalyova follows the stories of people who have nevertheless chosen to continue to live in Kharkiv. One, Adela Knapova, a writer from the Czech Republic who unexpectedly found love during a visit to this frontline city last year – and who uprooted her life in Prague to move to Ukraine to be with him. He’s an artist from Kharkiv, Konstantin Zorkin, who describes his belief in the transformative power of art and love.

These personal stories of love and life are intercut with the violence Russia continues to unleash on this city of over a million people. And they are set against a shifting geopolitical backdrop, of ultimatums and recriminations and talks, as all the while the attacks on Kharkiv and Ukraine continue.

Rising sea levels and a worldwide shortage of buildable land make the prospect of floating buildings and infrastructure more beneficial than ever. MAST is an architectural firm based in the southern harbour of Copenhagen in Denmark. Surrounded by shipbuilders and workshops, the MAST studio, run by two young passionate architects, devises and builds houses, community centres, saunas and whole neighbourhoods on water.

While many of their projects can be seen on the waters of Copenhagen, the team is inspired by the long tradition of waterborne dwellings across the world and are currently working on constructions in Thailand, the Maldives, the USA , India and Portugal.

Architecture critic and author Jonathan Glancey is invited to Copenhagen to see the studio in action and to travel out by boat to look at some of the completed projects.

Deep inside the Colombian Amazon hi-tech submarines are being built. When it comes to making the cocaine trade more profitable, there’s nothing narco-traffickers aren’t willing to try. Some of the solutions they’re reportedly employing sound like something out of the American TV series Breaking Bad: GPS-trackers, remotely operated submarines and recruiting highly specialised scientists. Reporter José Carlos Cueto of BBC Mundo has been investigating the new trends and technologies used by cartels in Colombia and abroad.

Labubu dolls, the elf-like plush toys from the Chinese toy maker Pop Mart, seem to have taken the world by storm. Singer Rihanna had one clipped to her bag, influencer Kim Kardashian shared her collection of 10 dolls on Instagram, and former England football captain Sir David Beckham also shared a photo of a Labubu, given to him by his daughter. So, what’s behind this craze? Fan Wang reports from Singapore.

From the US to the Middle East, sand and dust storms have recently swept across many parts of the world, colouring the skies and leaving people with breathing problems. These storms traditionally originate in vast deserts. However, scientists believe that climate change means more people could be affected - with desertification and melting glaciers, exposing more dust. Maria Zaccaro, a BBC journalist reporting for the Global Journalism Science and Climate team, finds out more.

Mumbai in India is one of the most densely populated cities in the world - and it’s also the perfect habitat for leopards. BBC Marathi recently posted a video on their YouTube channel, showing these majestic wild cats strolling down residential streets and even entering people’s homes. In the past, there were several reports of human-animal conflict, including some deadly attacks. But since 2022 there have been no accidents at all. So how did people and leopards manage to find a way to live together in harmony? Reporter Mayuresh Konnur has the story.

There’s plenty of chat on social media about so-called ‘grey divorce’. But are older people around the world really splitting up in record numbers?

The truth is it’s hard to be sure, because reliable figures on global divorce rates don’t exist. Where research has been done - most notably in the US - there’s some evidence that rising numbers of people are deciding to go their separate ways later in life.

We hear from three Americans, including 65 year-old Laura in Virginia. Her immediate feelings post break up - after almost 30 years of marriage - included loneliness and personal reappraisal.

“It was also a complete loss of my sense of identity,” said Laura. “I had my ex husband’s last name longer than I had my own name. I was a mother and my divorce coincided with my kids launching. So it was, okay, who am I now?”

For 68-year-old Steven in North Carolina, who split from his husband eight years ago, new relationships also required adjustment.

“It has taken time to rebuild that kind of trust on the emotional level,” he said, “and then taking your clothes off at 60 is different to taking your clothes off at 45!”

Two women from Malaysia and South Africa also reveal what grey divorce is like from an adult child’s point of view.

To Italians, bread is life. With 250 varieties across the country, it’s eaten with almost every meal. Its importance speaks to national values of community, tradition, quality and - above all - religion.

Australian-Japanese food writer Emiko Davies takes a tasty journey into the spiritual significance of bread in Italy, her adopted home. In the west of Sicily, residents honour Saint Joseph by constructing intricate sculptural breads, adorning altars with baked symbols, and staging a ritualised feast attended by the entire community. On the coast of Puglia, locals queue to receive blessed loaves in celebration of Saint Anthony. Finally, with food historian Fabrizia Lanza, she reflects on the origins of religious superstitions surrounding bread, and what the nation's diverse culinary traditions tell us about faith in Italy today.
