If you grew up with siblings, you might have noticed your family either adhering to or defying birth order tropes – think “the responsible eldest daughter” or “the invisible middle child”.

As it turns out, scientists reckon birth order might actually affect your health, wealth, and even IQ.

Here’s what the research says:

Some data suggest that first-borns are 13% less likely to smoke than fifth-borns, while first-borns are “more likely to be overweight, to be obese, and to have high blood pressure and high triglycerides”.

Meanwhile, first-borns seem likelier to have ADHD and/or autism than those born later. They’re also at a higher risk of food allergies and hayfever.

And second-borns may be more prone to substance abuse, migraines, shingles, and gut issues.

Firstborns seem to perform higher on IQ tests than their younger siblings, even in tests conducted as early as one year old.

Some think that might explain why oldest children could end up more successful and rich, too. A 2014 study found that eldest daughters are the most likely to succeed out of any sibling type; a 2012 study suggests first borns are more likely to hold leadership roles.

Last-borns seemed to be the most social and resilient, followed by first-borns, middle-borns, and only children in a study that quizzed parents on their kids’ qualities.

In the same research, middle-borns appeared the least happy.

Some think it might have to do with how parents treat each new child – perhaps the eldest gets the most emotional investment. “Firstborn kids get the undivided attention of their parents, whereas kids born later are often competing for parental time and resources,” NPR suggested.

Then, there are the peer groups of each sibling to consider. An only or eldest child looks up to their parents, while a younger sibling might “have role models who are slightly irrational two-year-olds, you know, their older siblings”.

With that said, birth order traits are far from universal, and not everyone agrees on how much of a difference it makes to things like intelligence and personality.

Actor and model Kellan Lutz has opened up about the “pressure” he felt while auditioning for Marvel films after his work in the Twilight movies.

In the latest instalment of the Inside Of You podcast, Kellan reflected on the period of his career after appearing in the billion-dollar-making franchise alongside Robert Pattinson and Kristen Stewart, in which he played the vampire Emmett Cullen.

During the interview, he revealed he was, at different stages, in the running to play Marvel superheroes Thor and Captain America after the Twilight franchise came to an end with the fifth film, Breaking Dawn – Part 2, in 2012.

“There were times even post Twilight when I was, you know, going out for Captain America and Thor and the pressure was really, really on,” he recalled of the iconic roles, which went to Chris Evans and Chris Hemsworth, respectively.

“I was like, I need to be so regulant and strict, and do this and do that. And then I’d get so bummed on myself.”

Kellan also shared that around this time in his career, he was feeling personally adrift.

“I lost Kellan. I lost that light,” he recalled about constantly chasing new roles once he was done with Twilight.

He shared that he became so “stressed and desperate” in this stage of his career that he lost sight of what was important to him. At one point, he even started talking with a deep voice to replicate his idol, Jason Statham.

“I would go into auditions thinking my voice was deep like that and sexy like that,” he admitted, before someone on his team pulled him aside to call him out.

Elsewhere in the conversation, Kellan claimed he had no idea how big Twilight would be when he first signed up to appear in it, and stated that he’s “grateful” that he got to even “taste of the dragon” and enjoy a level of fame many of his peers would dream of.

“A lot of people strive for that,” he claimed. “I still have friends who unfortunately… They gave up their families [to pursue a career in acting] They’ve sacrificed a lot – in unhealthy ways – to still chase this dragon of fame.”

Kellan concluded that he was happy with his current life, even if he has never donned a spandex suit to play an MCU hero.

“I like what I get to do. I like playing characters. It’s adult make-believe and I really do love it,” he told podcast host Michael Rosenbaum.

After the Twilight saga, Kellan appeared in 2014’s The Legend Of Hercules and The Expendables 3, in which he starred alongside his role model Jason Statham.

He also appeared in the crime drama FBI as Special Agent Kenny Crosby and the Taraji P Henson comedy What Men Want for Netflix.

In 2024, Kellan told Comic Book Movie: “I [would] love to do Marvel or The Avengers. I auditioned for Thor and Captain America. I got pretty close to those ones, but obviously Chris and Chris are brilliant for those.”

He added: “I don’t think I’ve auditioned again for a Marvel one, but I’d be open to doing another big franchise.”

A leading toy maker has promised to make changes to a controversial butt-shaped toy, which encourages children to squeeze, jiggle and spread the toy’s cheeks to elicit fart sounds.

Goliath, which created the ‘Butt Face’ toy – available to buy at Smyths, The Entertainer, Amazon and Asda – said it has listened to feedback from families and professionals who aired safeguarding concerns over the product.

Earlier this week, Dr Niamh Lynch, a paediatrician based in Cork and author of Should I Be Worried? A No-Panic Guide To Your Child’s Health, shared her worries over the toy, which has been marketed to children aged four and up.

“As a paediatrician, I would have a lot of safety concerns for children around this toy and the normalisation of this kind of play,” said Dr Lynch on social media.

“Because children learn through play, they learn what is acceptable and not acceptable through play – and this might break down boundaries and normalise playing with other people’s bottoms.”

In response to her video, people shared equal outrage over it. “I saw this in Smyth Toys the other day and I was seriously appalled. And anyone who bought that for a kid I would immediately suspect as a groomer,” said one commenter.

Multiple others called for the toy to be banned.

Elsewhere, on Mumsnet, one parent shared they’d spotted the product in their local Smyths store and “couldn’t believe it was real”.

They continued: “Am I being completely unreasonable, or is this incredibly inappropriate for early years? Children learn through play, and at age 4, they are just starting to grasp vital concepts like body safety, personal boundaries, and consent. Normalising this kind of interaction under the guise of ‘cheeky humour’ feels entirely wrong and confusing for toddlers.”

In response, a commenter said: “I can’t imagine who thought this would be a good concept for a toy – it’s really distasteful.”

Another described it as a “safeguarding nightmare”.

Some parents acknowledged that their kids would love it and they could understand why the product exists (“it’s grim but my 8yos would 100% want one”, said one), while others couldn’t see the problem.

“I don’t see the issue? I mean it’s tacky. And ugly. But children find bums funny. Obviously they don’t see them in a sexual way,” said another respondent. “Not saying I like this toy. But I can’t see how it could be harmful.”

Following a backlash in Australia, which saw a former child abuse detective warn that the toy could be misused by people seeking to normalise touching private parts or groom children, some stores pulled the toy from shelves.

Goliath has since told HuffPost UK that it has “decided to remove the stretch feature and change the age recommendation to 8+ years”.

“We are currently updating packaging and product design to reflect these changes,” the company’s spokesperson said.

“Ultimately, our aim is to create toys that bring families fun and laughter, while taking seriously the trust parents place in us when choosing toys for their children.”

HuffPost UK has contacted Asda, Amazon, Smyths and The Entertainer for comment.

One popular fan theory about the new Spider-Man movie Brand New Day is really starting to grab people’s attention.

In the lead-up to the film’s release, many people spotted a detail in the trailer that led them to believe that the Spider-Man comic book villain The Jackal could make his MCU debut, after they spotted Peter Parker and MJ at a party with a fictitious beer brand called the “Green Jackal” prominently displayed.

Some even suspected that Keith David might be playing the villainous character – and while this turned out not to be true, that hasn’t stopped people speculating as to exactly what the Jackal nod could have been all about.

Film fan Ivan Mars – whose posts as The Movie Detective have earned him 3.1 million followers on TikTok – has speculated that MJ’s new boyfriend, played by Star Wars actor Eman Esfandi, may actually be The Jackal in disguise.

“During the party scene where [MJ’s boyfriend] appears for the first time, there’s a beer keg labelled Green Jackal – but wait, he’s also wearing a green jacket,” Ivan pointed out.

“And if you look closely, the corners of his smile almost make his teeth look unusually sharp, just like The Jackal.”

He also reminded viewers that when Peter asks MJ how her new relationship is going, she tells him that her boyfriend is always telling her that she’s “withholding”, suggesting he might already suspect she has more knowledge about Spider-Man’s identity than he thinks she’s letting on.

“And we know Marvel never leaves these details there by accident…” he added.

Ivan’s video has now been viewed more than a million times across Tiktok and Instagram, with fans voicing their support in the comments.

“Not only that, but he was on Ned’s list of potential Spider-Man,” one TikTok user wrote, while another agreed: “Ned was suspicious of him being Spider-Man must be a reason for that.”

“Ooooohhhhhhh…..wow this is a great take!!!!” a different fan wrote on Instagram, while another Marvel fan conceded: “It is possible.”

“Dude got a sharp teeth and now he’s the goblin,” another Instagram user also joked.

While Marvel bosses are remaining tight-lipped about MJ’s boyfriend’s back story for now, one thing we can rule out is that he is actually Paul Rabin, another love interest of Peter Parker’s ex originally introduced in the comic books as the secret son of another Spider-Man villain, The Emissary.

“I am not, never have been, and never will be ‘Paul’,” the actor wrote on X earlier this week. “To those of you I saw in the comments defending my honour and saying I’d never accept that role… thank you and [may the force be with you].”

Spider-Man: Brand New Day is in cinemas now.

The UK’s leading energy supplier is encouraging the public to ‘power down’ during today’s eclipse.

The rare celestial event, which will see the moon obscure the sun by up to 95%, will take place between 6pm and 8pm, causing the sky to darken for a period of time.

During this point, a large portion of Britain’s solar power will be knocked out – just as millions of people are getting home from work and electricity demand rises.

To try and reduce the strain on the grid, Octopus Energy is urging the public to move everyday jobs outside the busy 6-8pm window – which means avoiding running certain appliances.

Octopus advised against running washing machines, games consoles and dishwashers during the eclipse – encouraging people to use them earlier or later in the day, where possible.

The following appliances can also use plenty of electricity in the home, so it might be worth turning them off at the plug, too:

• Tumble dryers
• TVs
• Ovens
• Electric showers
• Air conditioning units and fans.

Octopus noted that solar energy generated 14.4% of Britain’s electricity in July, “meaning a couple of hours without sunshine can leave a gap that has to be filled”.

According to the Guardian, today’s eclipse is expected to wipe out between 300 and 1,100 megawatts of solar power.

If enough households delay using electricity for a short period of time, it can “reduce the need to fire up extra gas power stations,” Octopus said in a press release.

The supplier said eligible customers who use less electricity than normal during the hours of the eclipse will earn free electricity the following weekend.

Depending on the weather and even your hormonal state, it can be completely normal to sweat at night.

In fact, the NHS said on its site, “Most people sweat during the night”.

Still, sometimes, it’s worth speaking to your doctor about it. Night sweats can be a symptom of menopause, low blood sugar, autoimmune disorders, thyroid issues, and more, per the Mayo Clinic.

And Dr Jiri Kubes, a radiation oncologist and medical director of the Proton Therapy Center in Prague, said, “During hot weather, almost everyone will experience warmer and more uncomfortable nights.

“That makes it very easy to overlook a symptom that might otherwise have prompted concern,” as it can rarely signal cancer.

Dr Kubes said that context and frequency matter here – sweating for one or two nights during a heatwave, for instance, might not be much to worry about.

“However, if unexplained night sweats continue regularly for more than two or three weeks, it would be sensible to arrange an appointment with your GP,” he said.

“People should seek advice sooner if the sweating is severe or appears alongside other concerning symptoms. You do not need to wait several weeks if you are feeling significantly unwell.”

The NHS agrees that you should see your doctor if night sweats happen “regularly”, if they wake you up, and/or if they worry you.

The extent of the sweating could say a lot, too – “If the room is cool but you are repeatedly waking with your pyjamas and bedding soaked through, that is different from simply feeling clammy on a hot night”.

Drenching night sweats have been linked to certain blood cancers, particularly lymphoma.

Night sweats that are “accompanied by unexplained weight loss, persistent fatigue, recurring fevers or a painless swelling in the neck, armpit or groin should be discussed with a doctor,” Dr Kubes shared.

Other warning signs include:

• painless lumps or swellings that do not settle,
• unexplained itching,
• breathlessness,
• persistent coughing,
• unusual bruising,
• infections that keep returning.

The oncologist stressed that most people with night sweats won’t have cancer, adding that swollen lymph nodes happen all the time due to illness and tiredness is common, too.

“These symptoms alone cannot provide a diagnosis. An overactive thyroid, for example, is a relatively common and treatable condition that can be identified through testing,” he ended.

“The message is not to panic after a couple of hot nights. It is to recognise a persistent and unexplained change, particularly when other warning signs are present.

“Do not simply wait for the weather to cool if the sweating is severe, keeps returning or is accompanied by other symptoms. A conversation with your GP can help establish whether further checks are needed.”

There’s a strong chance you know already, but there’s a pretty big solar eclipse happening later today (12 Aug) – and there won’t be another one like it until 2090.

The eclipse, which will see the moon obscure the sun by up to 95% (depending on where you’re viewing it from), will take place between 6pm and 8pm, causing the sky to darken for a period of time.

Health experts and the UK government have warned that you can’t look at the sun during this time without the right protection as it can cause permanent damage to your eyesight. Sunglasses won’t work either.

You can buy certified solar eclipse glasses, but if you didn’t order yours in time (or they were sold out), fear not! Here are a couple of ways you can watch the rare event safely.

There are two ways to do this.

Dr Shireen Ghezel, a GP, shared how to make a projector at home using a cereal box, some white paper and a square of foil.

Simply cut a strip of white paper and pop it at the bottom of the cereal box (this is what the eclipse will be projected onto). Then, cut out two slots from the top of the cereal box and pop a square of foil on one side, poking a hole through it with a biro.

When it’s time to look at the eclipse, turn your back to the sun and let the sun shine into the hole (via the foil). Peek into the box on the other side to see it projected onto the paper.

If you haven’t got a box to hand, you’ll need a biro, a piece of card and something to project the sun onto (a bit of paper would work).

In a video shared to Facebook, David Jones, a consultant ophthalmologist for Royal Cornwall Hospitals Trust, made a hole in a piece of card with his biro and then held the card up, facing the sun, with the piece of paper behind it.

The sunlight could be seen shining through the card and making a dot of light on the paper.

No recycling to hand? No problem! Grab a colander from your kitchen cupboard, stand outside and project the sun onto the ground through the colander’s many holes.

Jones said it’s his favourite method, as “you can make not just one picture of the sun, but a hundred all at once”.

Some people on social media have suggested using phone selfie cameras to watch the eclipse indirectly through their phone screens.

If you don’t have a special solar filter, there’s a risk that the intense sunlight can damage your camera lens, so generally this isn’t advised.

Supporters of Nicholas Hoult have complicated feelings about his next role.

On Tuesday night, the US broadcaster HBO confirmed that Hoult had been cast as Gilderoy Lockhart in the second season of its upcoming adaptation of the Harry Potter books.

The new Harry Potter series has already generated a lot of controversy due to the ongoing backlash surrounding the franchise’s creator JK Rowling, who is an executive producer on the show.

In the past few years, Rowling has become an increasingly divisive figure due to her views and commentary on issues relating to transgender people.

Of late, this has included deliberately and repeatedly misgendering transgender public figures, as well as donating tens of thousands of pounds to the campaign group which raised the initial legal challenge that led to the UK Supreme Court’s ruling last year that the legal definition of a woman should include only those who were assigned female at birth (and sharing a celebratory post of herself smoking cigar once the Supreme Court’s decision was reached).

As a result, many of Hoult’s fans were disappointed by the announcement that he’s accepted a part in the second season of the new Harry Potter show, voicing their feelings on social media…

Hoult began his career as a child actor, and revealed in 2024 that he auditioned for numerous roles in the original Harry Potter series around this time.

“I think I got to the point where I auditioned with [director Chris Columbus],” he recalled during an appearance on Hot Ones Versus. “He didn’t remember this, it wasn’t even a memorable audition. I think I said, ‘Hey, I auditioned for Harry Potter. Still waiting to hear back… I think I’m kind of going to age out of it soon’.”

He continued: “I remember doing a couple of auditions, and then meeting him and maybe having fake glasses for the audition. Not getting the role of Harry, and then maybe coming back and [them] being like, ‘Will you audition for Malfoy?’. I don’t think I got that either, and then they were like, ‘just gradually audition for every role in Harry Potter’ until they were like, ‘No’.”

The first season of Harry Potter will premiere on Now, Sky and HBO Max in the UK later this year.

In the run-up to its release, numerous cast members have spoken about their decision to take part in it, often while distancing themselves from Rowling and her views.

John Lithgow admitted earlier this year that he considered quitting the series – in which he will play Hogwarts headmaster Albus Dumbledore – when he began to face criticism over his involvement, but ultimately decided to remain a part of it.

Meanwhile, Nick Frost, the new Rubeus Hagrid, also maintained that his and Rowling’s views on trans issues “don’t align in any way, shape or form”.

And just this week, Bel Powley took part in an interview with The Telegraph, in which she said: “I think that the trans community deserve safety and dignity and respect and total acceptance. But I love Harry Potter.”
