We want to hear from people in their 60s, 70s, 80s or even 90s who are actively dating other people over the age of 60

We’d like to hear from both single people and members of couples who very recently met the love of their life on a date. What is the best and worst date you’ve been on? Any funny or shocking anecdotes to share?

How do relationships compare to the ones you had at a younger age? How much does companionship or sex factor? What about exes – your’s and your partners’ children and grandchildren? Are you using apps and websites or relying on word of mouth? Have you been on a lot of dates? What about ghosting?

In his inimitable fashion, Herzog follows a South African naturalist’s quest to discover a new species of elephant in Angola

Werner Herzog has once again shown his flair – his genius, perhaps – for locating passionate quests and obsessions at the limits of the imaginable. This new film is about South African naturalist Dr Steve Boyes and his mission to discover if there is a hitherto undiscovered mega-species of giant elephants, or “ghost elephants”, living beyond the human gaze in the vast highland plateau of Angola. He also wants to see if these fugitive elephants – if they exist – are genetically related to a particular huge elephant, the biggest on record, which is on show at the Smithsonian National Museum of Natural History in Washington DC, named the “Fénykövi” elephant after the hunter who shot it in 1955.

Boyes has been nurturing this hunch for many years. It is not clear what the scientific basis for his hypothesis is, but he is in constant touch with Kalahari bush trackers in Namibia, whose instinctive understanding of elephants has led him to this vision. He and his team conduct an expedition into Angola, intent on finding the “ghost elephants” and getting a DNA sample to take back to the Smithsonian – rather like a Jurassic Park movie – having first gained permission to do so from a tribal king in a ceremony treated without mockery.

Living – or crocheted – canopies and a 3,000-year-old Persian technique are among methods being used to cope as temperatures soar

As Spain takes a breath after yet another brutal summer heatwave, with temperatures above 40C in many parts of the country, the residents of the sherry-making town of Jerez de la Frontera have come up with a novel way to keep the streets cool.

Green canopies of grapevines festoon the town, reducing street-level temperatures by as much as 8C. “We’re planting vines in the old city because we hope that in two or three years we’ll be able to brag that this has put an end to stifling temperatures,” said Jesús Rodríguez, president of Los Emparrados, a group of residents who aim to beautify and green the city’s streets.
