It’s the canine equivalent of gentle v tough parenting – and there is no sign of a ceasefire. So what is the correct way to get man’s best friend to behave?

Obama has been accused of ‘snobbery’ over his Trump diss, as people rush to defend the restaurant chain’s ‘affordable opulence’

Around lunchtime on Tuesday, a Rolls-Royce stopped at the intersection of Beverly Drive and Dayton Way in Beverly Hills, California. Local people in athleisure walked past Balenciaga, Dior and Prada boutiques, as visitors on Hollywood bus tours ogled nearby Rodeo Drive, where Burberry and Louis Vuitton shops meet at a celebrated street corner.

Up the street, across from the upmarket Erewhon grocery store – home to $21 smoothies – a few diners sat outside an American landmark: the Cheesecake Factory.

In wet weather, garden snails can seek shelter in letterboxes – and find a feast there waiting for them

We’ve all heard of snail mail – a term popularised since the advent of electronic mail – but who knew that snails eat mail?

We have it on good authority from the ecologist Simon Mustoe – who said snails ate his letter from Sir David Attenborough – a BBC report announcing the closure of a Northumberland Royal Mail postbox because of snails “munching the mail”, and desperate people on the forums of the Australian hardware chain Bunnings claiming snails have “a real appetite for postal letters” and can “eat a whole letter in two days”.

Food safety campaigners have long been concerned about pesticide residues on lemons, limes and oranges – and now a social media post about it has gone viral. How safe is it to eat lemon cake or drink a G&T with ice and a slice?

Do you sprinkle citrus zest on to your cooking or drink hot water with a slice of lemon? According to an Instagram post that went viral last week, you shouldn’t. “Select citrus fruits at Lidl now come with a ‘Peel unfit for consumption’ warning,” posts @wholefoodwarrior. She photographs some of the supermarket’s labels, which list the post-harvest chemicals used to conserve the fruit: azoxystrobin and fludioxonil (limes) and imazalil, 2-phenylphenol, thiabendazole, pyrimethanil and fludioxonil (easy peelers), plus E903 in the peel’s wax coating (both).

The 10,500 comments on the post are largely appalled. So what are these substances? And how worried should consumers be?

Thanks to Jilly Cooper, tartan and tweed, waxed jackets and wellies are a style vibe right now

British heritage, in fashion terms, is a country where it is permanently October. A conker-brown and pleasant land, if you will. Brand Britain in the style sense comes into its own in autumn: roaring fires, muddy lanes, damp dogs. Waxed jackets and chunky knits, tartan and tweed, jaunty scarves to banish draughts. Clothes for going on a hearty walk, but with a hip flask in your pocket. Fashion has been mining this seam since long before Brideshead Revisited made battered evening dresses and Oxford bags look romantic, and it keeps returning, because trad British style is satisfyingly utilitarian while also being loaded with enough backstory (class, history, eccentricity) to be intriguing and reinventable.

Also: Rivals. It has taken considerable restraint for me not to mention Rivals in the whole of the first paragraph, because it is now a matter of mere weeks until we get our next Jilly Cooper fix and I, for one, cannot wait. Cannot wait for Cameron stalking the corridors in her foxy power suits, for Taggie in her cute jeans and jumpers, for Valerie in head-to-toe tweed and an aggressive amount of blusher. The success of Rivals has done for old-school British dressing what Emily in Paris did for the beret, only with better jokes and more adultery. Jolly hockey sticks style is the new French girl chic. This fantasy is homegrown, which makes it both more embarrassing and harder to resist. Just as Emily and her friends and frenemies are a camp send-up of fashionable Paris, Rivals is a fond, nostalgic semi-parody of the British wardrobe. The show’s costume designer, Ray Holman, has drawn on original 1980s pieces from Dunhill and Mulberry for inspiration. With Liberty fabrics, nods to polo uniforms and sturdy waxed coats, he has brought the Sloane ranger back into the fashion conversation for the first time in years.

The untamed, magical landscape takes in a vast national park, palatial houses and a sculpture garden and museum stuffed with Van Goghs – all easily accessible by bike

One minute I’m cycling through an expansive dusty pink stretch of heathland with sloping sand dunes in the distant horizon, the next I’m winding through a fragrant Scots pine forest as sunlight filters through the branches of red-barked trees to make a kaleidoscope of white shapes on the trail floor ahead.

I’m in Hoge Veluwe National Park, a 5,400 hectare (13,000 acre) nature reserve in Gelderland, about an hour and a half from Amsterdam. It’s crisscrossed by 25 miles (40km) of cycling paths, and around 2,000 free-to-use white bikes are available for visitors to explore the ever-changing scenery.

On the eve of my 40th birthday, I was doused with cold water at a train station. Before, I would have shrugged it off. But suddenly I realised it was time to assert myself

It was the evening before my 40th birthday – a freezing cold night in March – and I was travelling across London to meet some old school friends for dinner. As I walked down the stairs into the tube station, I spotted a few teens leaning over the balustrade above me. I thought nothing of it; teens hanging about aimlessly is as classic a combination as Archers and lemonade. That was, until they each threw a few KFC paper cups’ worth of icy water over my head.

I noticed it in slow-motion and, at first, kept walking. Then I realised that my hair was wet and so was my back. Without thinking, I ran back up the stairs and followed the teens, who were marching off down the main road. People on the street were watching me, obviously intrigued to see what I was going to do. What was I going to do? A few people looked at me with pity and pointed me in the right direction.

It involves the fracturing of a patient’s ribs, before they spend three months laced into a corset. Some of those who have had this cosmetic procedure say it is like being ‘hit by a bus’. Why is it becoming more popular?

Daniela Cesin was 14 when she began thinking about her looks. “I was a little bit chubby and I started to work out at home and lose weight. I saw the difference in my body: my abs, the muscles in my arms, and I started liking it,” she says. By 31, she had the slim, toned body she had hoped for, but something was still missing. “I wanted to have that guitar hourglass shape.”

In August, Cesin travelled from Miami, where she has lived for the past 15 years, to her native Venezuela for liposuction and a fat transfer to her hips. She met her cosmetic surgeon for the first time the day before the procedure, and he realised she didn’t have enough fat to go ahead with it. Instead, he offered to perform RibXcar: a rib remodelling surgery that would involve fracturing three of her lower ribs on each side and binding them in a corset for three months, to set the ribs in a new position and give her a wasplike waist.

As the weight-loss drugs become more common, some runners find the side-effects challenging. Here’s what experts say

• Women: was your autoimmune condition misdiagnosed?

Keri M, a marathoner in her 50s, knew the race would be terrible.

This feeling couldn’t be chalked up to inexperience. Keri, who asked us to omit her full name due to the sensitive subject matter, has completed dozens of half marathons and four full marathons.

We’d like to hear from people who’ve found love in later life

Getting older doesn’t need to mean the end of romance – and for some, it is just the beginning. Although relationships might look a little different after the age of 60, many people successfully find new love, companionship and connection in their later years.

With this in mind, we want to hear from people whose love life has been renewed after the age of 60. How does love in your sixties and beyond differ from romance in your twenties or thirties? Perhaps you’ve come out later in life, and started dating someone of the same gender? Or maybe you’re in love for the first time, and just discovering all that it has to offer?

In her new book, Envy, Stacy Kim explains how to understand the feeling, identify your deeper desires and use them to achieve your goals

In the 16th-century poem The Faerie Queene, envy is a ghoulish figure riding a ravenous wolf, sad to see the fortune of others and “wonderous glad” of their hardship. It’s not a flattering depiction; better to be thankful for what we have, rather than dwell on such a bitter and self-destructive feeling, right?

Maybe not. “I think that when we don’t examine our envy, that’s when it leads us astray,” says Dr Stacy Kim, social scientist, life coach and author of the new book Envy: Why Wanting What They Have is the Key to Getting What You Want. Kim wrote the book after seeing the way envy came up for her coaching clients and reflecting on the role it had in her own life. The book is informed by social science and philosophy research, as well as her personal and professional experiences.

Similar target: “You remind yourself: ‘Hey, the reason why I’m feeling this envy is because what I want is within my reach,’” she says.

Intangible desire, as mentioned above

Relevant comparison: Identify which specific domain – something you care about or already participate in – is relevant to your desires

Negative emotion: How long does it last? How intense is the message it’s sending? This tells us how important the feeling is.

I spent time in some of the greatest art institutions with groups of self-funded retirees. But a vacation it was not

• Read more in the a job that changed me series

In 2012 I was living in Sydney, halfway through the shelf life of our annual theatric political satire The Wharf Revue, although I didn’t know that at the time. I was also doing some work for the Art Gallery of New South Wales, hosting panel discussions and interviews, when a colleague asked if I would be interested in co-leading a guided tour to New York, focusing on art and theatre. Of course I said yes.

Handling the art side of things was my gallery colleague Brian Ladd and together we landed in a wintry Manhattan in January with about 25 guests largely, shall we say, a certain demographic who were keen to sample the cultural delights of the great metropolis.

Adding gratuity doesn’t always make sense, but the obligation to has been entrenched as a societal norm

You arrive at a pizza place to pick up your order. The credit-card screen asks if you would like to tip and gives some choices. It seems strange to tip the cashier, who did nothing but hand over the pizza. But it also seems a little harsh to select “no tip” instead of one of those more generous options.

What’s the right thing to do?

Before being rescued, he had an extremely traumatic experience. You’d never know it though, from the joy his patience and sunny nature bring to those who most need him

In December 2024, my kerry blue terrier, Magnus, died suddenly from a stroke at the age of nine. Devastated, I started looking at rescue dogs on Facebook and came across Clement, who was being looked after by a shelter in Romania. It wasn’t his appearance that caught my attention, but his heartbreaking story.

An eight-year-old mixed-breed rescue, Clement had spent most of his life with a woman living with Alzheimer’s. One day, she accidentally let him out. He was hit by a car, attacked by two large dogs and left in a ditch for three days in the snow before being rescued by chance. When I read this, I knew I had to take him in.

Faced with a stagnant jobs market, many are spurning children or pets in favour of ‘raising bricks’

Young adults in China looking for a cheaper, low-maintenance alternative to having children or pets have found an answer: raising bricks.

Bricks may not be as cuddly as cats or as life-affirming as human offspring, but they also cost next to nothing. “No cats, no dating, I started raising a brick,” wrote one brick parent on social media.

It might dry out a pimple, but it could make things worse, so it’s worth exploring other solutions

The idea that toothpaste can be used to treat spots has been around for years. But does it actually work – or could it make things worse?

“A spot happens when a sebaceous gland gets plugged and inflamed,” says Dr Rosalind Simpson, a consultant dermatologist and associate professor at the University of Nottingham. Acne develops through a combination of blocked pores, increased sebum production and changes in Cutibacterium acnes, bacteria that naturally live on the skin.

A new report has found many crops are far less nutritious than they once were, so we need to eat more of them. Here is how to get your five portions of fruit and veg a day, easily and affordably – and potentially increase that to ten

When Eva Humphries first started working as a nutritionist, she met a client who had just found out he had high blood pressure and high cholesterol, and was on the verge of type 2 diabetes. He had no idea how to change his diet or lifestyle.

The man broke down and cried for 45 minutes, leaving Humphries with “no idea of what to do”, she says. In the final 15 minutes of the session, scrambling for a quick but helpful message, she finally said: “When you look at a plate of food, can you just make half of it veg for me?”

Your feelings are understandable. Exploring and accepting them may help you move on

I was with my ex-partner for more than 20 years. We were mostly happy and I expected us to be together for life. For well over half the relationship, I was the sole breadwinner and, at my ex’s request, managed our finances. We were reasonably well off, with savings and without a mortgage. We even had a holiday home, albeit a static caravan.

I retired early, and the problems we had in our relationship grew. We had both loved travel, but I was repeatedly told we couldn’t afford it, which I knew was nonsense. I went back to work in a demanding new field, but my ex showed no interest. I spent more time away from home and began therapy (my suggestion of couples’ therapy was rejected). After a year of therapy, I said I was leaving.
