Bill Gates explains the ‘safest’ age to give a kid a cellphone

Sorry, kids.

kids and technology, parenting, Bill Gates, cellphones

Bill Gates in conversation with The Times of India

Bill Gates sure is strict on how his children use the very technology he helped bring to the masses. In a recent interview with the Mirror, the tech mogul said his children were not allowed to own their own cellphone until the age of 14. "We often set a time after which there is no screen time, and in their case that helps them get to sleep at a reasonable hour," he said. Gates added that the children are not allowed to have cellphones at the table, but are allowed to use them for homework or studying.

The Gates children, now 20, 17 and 14, are all above the minimum age requirement to own a phone, but they are still banned from having any Apple products in the house—thanks to Gates' longtime rivalry with Apple founder Steve Jobs.

While the parenting choice may seem harsh, the Gates may be onto something with delaying childhood smartphone ownership. According to the 2016 "Kids & Tech: The Evolution of Today's Digital Natives" report, the average age that a child gets their first smartphone is now 10.3 years.

"I think that age is going to trend even younger, because parents are getting tired of handing their smartphones to their kids," Stacy DeBroff, chief executive of Influence Central, told The New York Times.

James P. Steyer, chief executive of Common Sense Media, a nonprofit organization that reviews content and products for families, additionally told the Times that he too has one strict rule for his children when it comes to cellphones: They get one when they start high school and only when they've proven they have restraint. "No two kids are the same, and there's no magic number," he said. "A kid's age is not as important as his or her own responsibility or maturity level."

PBS Parents also provided a list of questions parents should answer before giving their child their first phone. Check out the entire list below:

  • How independent are your kids?
  • Do your children "need" to be in touch for safety reasons—or social ones?
  • How responsible are they?
  • Can they get behind the concept of limits for minutes talked and apps downloaded?
  • Can they be trusted not to text during class, disturb others with their conversations, and to use the text, photo, and video functions responsibly (and not to embarrass or harass others)?
  • Do they really need a smartphone that is also their music device, a portable movie and game player, and portal to the internet?
  • Do they need something that gives their location information to their friends—and maybe some strangers, too—as some of the new apps allow?
  • And do you want to add all the expenses of new data plans? (Try keeping your temper when they announce that their new smartphone got dropped in the toilet...)

34 broken bones, a mural, and Buddy the Elf—what these three things have in common
True

The Bank of America Chicago Marathon took place on Sunday, October 12th. Every runner who took on the enormous feat of 26.2 miles is truly an inspiration. We’re proud to share three outstanding stories about the power of community, giving back and crossing the finish line. Not only did they run an outstanding distance, but they each also gave back by fundraising for an organization that changes lives for the better.

Running a marathon is so much more than race day. It’s sticking to a schedule, getting enough rest, learning how to fuel your body for long distances, and—perhaps the most challenging of all—building mental resilience.



Meet Leanne: Running after 34 Bone Fractures

Leanne was only 12 years old when during her middle school cross country practice, she fractured her right tibia, the shin bone in her leg. This wasn’t Leanne’s first time breaking a bone—it was actually her 34th fracture. After many years of being overlooked as "clumsy," Leanne felt immense relief and recognition when a doctor diagnosed her with brittle bone disease, an incredibly rare condition.

Lurie Children’s provided a care plan for Leanne to build strength and start running again. And as of October 12th, Leanne ran her second Bank of America Chicago Marathon. She said in an interview, “I never thought I’d run again. But against the odds, here I am, training for my second Bank of America Chicago Marathon... all because of Lurie Children’s.”

Leanne’s impressive journey is a testament to the incredible research of Lurie Children’s, where she gives back by volunteering at the hospital and running on its behalf. Talk about being a true inspiration.


Meet Everett: Running to Inspire Through Art

Everett is an artist who creates beautiful murals around the city of Chicago. He uses his art as a tool for storytelling for community and connection.

In addition to being an artist, Everett is a runner. He ran the 2025 Bank of America Chicago Marathon on behalf of Peace Runners 773, a non-profit organization that strengthens the community of Chicago. In this video, we follow Everett on a run to visit some of his favorite murals. The run ends at Garfield Park, where Everett just finished a mural that he dedicated to the organization—symbolizing growth, strength and togetherness. Everett didn’t stop there.

While building his strength as a runner, Everett is strengthening his city of Chicago. Through his running and artwork, Everett has brought more awareness and resources to his community.

Meet Joseph: Running on Behalf of Special Olympics


Joseph ran the Chicago Marathon on behalf of Special Olympics, dedicating each mile to one of 26 friends with a developmental disability. The last 1.2 miles were extra special. It was for one of his closest friends, Matt.

In this video, Joseph runs to Matt’s house. For every mile of this training run, he tells us a heartwarming anecdote about Matt. They met at camp and soon, Matt will be a groomsman in Joseph’s wedding. The duo even sends a Christmas card every year—most notably dressing up as Buddy the Elf and sharing a bowl of spaghetti with maple syrup (spoiler: it doesn’t taste good).

As Joseph runs, he says, “Before we get to Matt, a quick note about why I’m running on behalf of Special Olympics. Matt and I love sports. And so do many of my other friends. Donations help provide year-round sports training and competition for more than 20,000 people with intellectual disabilities across Illinois.”

Joseph is the perfect example of inspiration. Not only did he run an entire marathon, but he also found inspiration in his friends who love sports as much as he does.


Leanne, Everett and Joseph are three incredible people who have shown how much strength and perseverance it takes to run a marathon. Each runner is both empowering themselves and their community. Their dedication to the Bank of America Chicago Marathon shows that the people of Chicago have a passion for the city, their neighbors and their personal achievements.

American shares his 9 realizations about the U.S. after 13 years abroad and it's eye-opening

“If you’ve never left, you can never understand what it’s really like…”

You learn a lot about your country when you leave it for a while.

Evan Edinger moved to London over 13 years ago to study abroad but never planned on staying overseas permanently. His goal was to get his degree, return to the United States, start his career, and make a life for himself. He thought of his time in London as a "temporary adventure."

But when he finished his degree, he found himself in an unexpected situation: He didn't want to go back. "The longer I stayed in London," Edinger shares on his YouTube channel, "the more I began to notice all of the assumptions that I'd grown up believing in America, the things I was brought up to believe were undeniably true and just the way the world worked—it turns out they weren't true at all."


One of the benefits of living in another country is seeing your country of origin through different eyes. That perspective can cause you to appreciate some things and question other things. Edinger shares nine realizations he's had about the U.S. since he left, starting with one of the most quintessentially American realities he found himself questioning.

- YouTube www.youtube.com

1. Guns

Edinger grew up in New Jersey and describes it as "quite a blue state," but he was still immersed in the gun culture that views gun ownership as a fundamental part of being an American.

"I was raised in a very pro-gun household," Edinger says. "In my family home in America, we had a 12-gauge shotgun, a 10-gauge, a black powder rifle, and a .410 shotgun for the children. My dad would take us out some days to shoot empty cans of beer or play pigeons or sometimes go hunting for pheasants or deer."

He says the notion of not owning a gun was unthinkable in his upbringing. "The idea that other countries do not allow guns is viewed more like these other countries are missing a fundamental right," he says.

His ideas about guns have changed dramatically since moving to London and living in a society without ubiquitous access to guns. "Visiting Philadelphia when I was younger was always scary to me because I never knew who had a gun, who wanted to rob me," Edinger shares. "Visiting New Orleans a couple years ago, I was told by my hotel staff that a few days prior, a tourist was shot and died in the local Popeye's Chicken because he caught a stray bullet of two people having an argument in the restaurant. So, that's just something that people just have to deal with. This constant fear of I could just die being caught in a crossfire and there's nothing I can really do about it because freedom. I've pretty much never felt that level of fear in London at all. And that alone was enough to sway my opinion on guns."

2. Government

"One thing that's really drilled into you pretty much every year of American school is that American democracy is the end-all be-all of government and that it is the beacon of freedom other countries look to emulate. Then, once you become an adult and you see how dysfunctional the U.S. government is, you search for anything to feel better about it and usually settle on 'Well, at least it's not a third world dictatorship.'"

But those aren't the only two options. Edinger explains how the parliamentary system in the U.K. is far from perfect, but it tends to be more effective at actually getting things done because lawmakers aren't constantly stymied by the inherently destructive two-party gridlock we have in the U.S.

"It's messy, yes, but after 13 years away, I've come to the belief that no system of government is perfect," he says. "But most systems in Western Europe are far more effective than what I grew up believing was the 'best in the world.'"

3. Walkability and Public Transport

In the U.S., having a car is practically a symbol of freedom, but Edinger says he's never felt the need to have a car in his 13 years living in London. He says it's been incredibly freeing to be able to walk and take public transit everywhere, and not just in the city. He's been able to travel all over Europe, in larger cities and small towns, and the focus on walkable neighborhoods and public transportation is everywhere.

"After having spent some time living in walkable neighborhoods, I would never ever choose to live in a car dependent place ever again," Edinger says. "It is truly one of the most life-changing parts of living over here. And because I'm always walking everywhere, because I'm always cycling everywhere, it's so much easier to be healthy and physically fit without even trying."

4. Food Quality and Price

Europe has different regulations than the U.S., Edinger explains, with an approach that leads to a lot less additives and chemicals being added to foods.

"Europe's food agency focuses on possibilities and the U.S.'s focuses on probabilities. Is it possible an unnecessary additive could be harmful? Europe prohibits it just to be safe. The US agency, the FDA, they only step in if the probability of it being harmful is high. So, that risk is passed on to the average American consumer."

Edinger also points out that the ability to walk down to the store to get fresh ingredients regularly makes it a lot easier to eat well. "It's one of those things where once you experience both, there is no contest. No contest. So, it's much easier to be healthy in Europe than in America."

5. Healthcare in the U.S. vs. Europe

"If my health does have issues, I am glad it's not something that would ever bankrupt me or cause me to ever think about how much it would have to cost me just to be sick," says Edinger.

Americans often hear horror stories about socialized medicine, but Edinger's experience with going to the doctor and even going to the hospital have been positive, and barely cost him anything.

"There are only two types of people that are against the freeing social safety net that is universal healthcare," says Edinger. "People that have never experienced socialized healthcare and people that profit from the broken system. That's it." Most Americans want it, but "most Americans" is not where the money is.

6. Consumer Protections in the U.S. vs Europe

Edinger shares that he bought a MacBook Pro in 2019 that didn't work right, and he hadn't purchased AppleCare because he knew he didn't have to.

"If you buy a tech product in Europe, you have a reasonable expectation that it should last you at least two years free of defects," says Edinger. "And if it's not up to your expectations or breaks down before then, you can demand a return or replacement. This law protects consumers from shady business practices."

He ended up getting his full money back on the computer due to those consumer protections.

"It's laws like this where you really begin to notice a pattern that life in Europe is one that gives more rights to the everyday person over giant corporations and shared benefit over private," says Edinger.

7. Worker Rights

"A quick summary would be 28 days minimum paid holiday, one year paid maternity leave, two weeks paid paternity leave, sick leave, even the right against unlawful termination," said Edinger. "When working part-time at Urban Outfitters in London, even though I worked less than 20 hours a week, I still got two days paid holiday per month. That's insane, right? No, that's just life over here. Meanwhile, I worked five years at a Pizza Hut in New Jersey for over 30 hours per week. Never got a single day of paid vacation."

Indeed, there's more than a handful of European countries that guarantee at least a month of paid days off, with some countries actually requiring a certain number of days or weeks off.

Edinger points out the irony that he was always taught that the U.S. was for the individual, for individual freedoms. But in his experience, in Europe individuals have more rights than those with money or power, while it's the opposite in the U.S.

8. Money (Live to work or work to live?)

Edinger says that most things are more affordable in Europe, from groceries to data plans, but Americans do earn higher salaries.

"So if you earn a lot of money and money is your sole defining metric of success, then you can feel a lot more successful in the U.S.," he says. "But because the culture in Europe is work to live and not live to work, you might find that the stress and cost tradeoffs and quality of life erode the value of that higher salary quite quickly."

9. On Romanticizing Europe

People often wonder if Americans romanticize Europe too much, and Edinger says the same question used to be asked of Europeans romanticizing America. But now that we have YouTube and social media and a better ability to see the realities of both places, he says what Americans "romanticize" about Europe is really just the things we want and don't have.

work-life balance, united states, working, european culture, worker rights Work-life balance is something a lot of Americans struggle with.Photo credit: Canva

"I think most Americans who are eyeing up Europe are doing so because of the things that America is lacking. Nearly two in three Americans want universal healthcare. Well, America doesn't offer that. Again, two in three Americans want European style vacation policies. America doesn't offer that. And 53% of Americans would prefer to live in a walkable neighborhood, but sorry, America doesn't offer that. The list goes on. If America were an actual democracy, I don't think many of these people would be having romanticized views of Europe at all because they wouldn't need to. They could have everything they wanted in the country they were born and raised."

Of course, every country has its problems and there are certainly downsides to moving abroad. Edinger acknowledges that but says it really boils down to what you value in life. Americans are taught to romanticize the U.S., and leaving it helps you see the reality, what's good about your country and where it has room for improvement.

"I think the main thing though out of everything that I miss about the U.S. that I can't really get here is not rights, not freedoms, not anything that's big on quality of life improvements," says Edinger. "It's just Mexican food and good ice cream."

15 nostalgic foods kids thought were super 'fancy’ but as adults realized were decidedly average

"When you’re eating leftover chicken casserole and spaghetti most nights, Red Lobster felt like fine dining."

grey poupopn, red lobster, andes mints, 1980s, nostalgic food, classy food, fancy food, middle class fancy

Red Lobster, Andes mints, and Grey Poupon mustard.

Kids don’t have the most incredible sense of what’s truly fancy and what is just excellent marketing. That’s why when you get older, a strange feeling hits where you wonder, was this restaurant ever really fancy at some point, and got worse? Was it never really that great to begin with? Or did it only seem great because we didn’t have much money growing up?

To make things a bit more confusing, social class, culture, and money are all relative, so what’s fancy to one person may seem a bit down-market to another. Further, status symbols and trends change over time, so a type of food that was seen as a delicacy 30 years ago may be seen as gauche in 2025.


A group of Redditors got together to discuss the foods they enjoyed growing up that they definitely thought were fancy as kids, but when they got older, they realized they were a lot less impressive than they thought. A Redditor posed a question to the AskReddit forum: “What food did you think was fancy as a kid but now you realize it’s trash?” The responses ranged from restaurants that haven’t stood the test of time to mass-produced food products that were positioned as upscale but clearly aimed at the average consumer.


15 nostalgic foods that seemed 'fancy' when we were kids, but as adults, aren't so great

1. General Foods International Coffees

"Basically, the sugary powder mix 'cappuccino' you can now buy from a machine at the gas station."

"My mom would keep the tin she had hidden in the cabinet so neither me nor any of my sisters could get it, which gave it an extra air of fanciness."

2. Andes mints

"Those Andes mints that all come individually wrapped. My aunt, who had a nice house, always had them, and we never did at home, so I thought it was a rich people thing."

"I mean they aren't fancy but they're definitely not trash. If you like mint and chocolate they're just as good as any other candy."

3. Salisbury steaks

"Those Salisbury steaks that you reheated in the oven for 15 minutes. If you had 2 you were in trouble."

"Salisbury steaks! I thought they were a made-up food! Explanation: non-American here, but have played a computer game (Fallout4) where Salisbury steaks are involved. I always thought they were just a made-up thing for the game."

For the uninitiated, Salisbury steak has a fancy name, but in reality, it's just ground beef, shaped into a steak with rich, thick gravy doped all over it. It's basically a dressed-up hamburger without the bun. The dish was named after Dr. James H. Salisbury, a 19th-century American physician who believed that a diet rich in minced meat was good for your health.


4. Chicken and red stuff (Catalina dressing)

"We had a meal growing up called Chicken and Red Stuff. It was my favorite meal, and anytime we had it I was a happy kid. You made it by placing a cut-up whole chicken into a baking pan and poured a bottle of Catalina salad dressing on top. Not Catalina Lite - you could f*** right off with that sh** - it had to be regular Catalina dressing. You then cooked the chicken in the oven for an hour at 350 degrees. When the chicken was done you would take it out of the oven and remove it from the pan. This was the chicken in Chicken and Red Stuff. You would then pour the drippings from the pan into a gravy dish. This was the Red Stuff in Chicken and Red Stuff. You would serve the chicken with a side of elbow macaroni and pour the Red Stuff on top. There would also be a salad, and of course, Catalina (still one of my favorite salad dressings) would be available."

5. Individually wrapped butter

"I thought the little individually wrapped butters you get in hotels were the height of sophistication, so my grandmother always bought them for when I visited. They aren't trash, but they are just butter."

"They were, however, a thousand times better than the margarine we had at home."

6. Pepperidge Farm cookies

"The packaging, the cool names, the crimped paper separating the layers… so fancy."

"Those cookies have had serious shrinkflation. Half the size they used to be."

7. Kid Cuisine

"Cuisine is such a fancy word."

"With the brownie!"

"And the corn always somehow got in the brownie/pudding by the time your parents set it in front of you!"


8. Imitation crab meat

"I thought I was having lobster in my bag lunch in elementary school."

9. Red Lobster

"But…cheddar biscuits!"

"We didn’t have a lot growing up. We weren’t poor, but we weren’t wealthy either. Lower-middle class. We didn’t go out to eat often, but once a year, after wrestling season was over, we’d go to Red Lobster, and we were able to get whatever we wanted. As a kid, I felt like we were eating at a Michelin-star restaurant. When you’re eating leftover chicken casserole and spaghetti most nights, Red Lobster felt like fine dining."

In May 2024, Red Lobster filed for Chapter 11 bankruptcy due to mistakes, including the costly "endless shrimp" promotion and shifts in consumer dining habits. But the chain is now enjoying a remarkable turnaround after hiring 36-year-old Damola Adamolekun, the youngest CEO in the restaurant's history.

10. Entenmann's

"Thought they were the peak of luxurious baked goods."

"Don't you dare slander Entenmann's. That chocolate-covered donut with a nice, light, crisp still goes hard today. The fudge cake, those chocolate chip cookies, and the lemon cake are all straight delicious. Unfortunately, I now live in FL, so the doughnuts melt together, but as soon as it gets cold for 6 days here, I'm gonna enjoy!"

11. Summer sausage trays

"Those 'summer sausage' trays with the big cheese balls that are coated in chopped nuts, I think? Like an '80s midwestern version of a charcuterie board."

"Oh, god, yes. I thought they were fancy for longer than I care to admit - like proudly gave them as gifts and stuff in my twenties."

12. Grey Poupon

"Remember those stupid commercials?"

"Vividly. And because I was a Gen X kid that loved Wayne's World, I used to think asking cars next to me at a stoplight if they had any Grey Poupon was just peak comedy in 1992 when I got my driver's license."

"Hey, compare Grey Poupon to most other Dijon mustards, it's got a lot more bite. It's damn near horseradish-esque."

Grey Poupon is still around, but the product is forever tied to the 1980s commercials featuring affluent people in Rolls-Royces exchanging bottles of the spicy mustard.

13. The International House of Pancakes

"The Funny Face was the pinnacle of fine kid dining."

14. Ambrosia salad

"We only ever had it at 'fancy' events — birthdays, holidays, weddings, etc. — and it was called fu**ing Ambrosia. I thought it must be some super expensive luxurious dish. Turns out it's Kool Whip and fruit and marshmallows."

"Since I moved to France, I’ve been dying for a taste of midwestern jello salads. They’re truly awful but comforting."

15. Instant ramen

"When I was a kid, I thought instant ramen was the height of luxury. That little flavor packet felt like fine dining in a silver sachet. I used to sit there slurping noodles like I was in some five-star Tokyo restaurant. Now, every time I see it, I can practically taste my student debt and regret."

"I recently stopped eating Mr. Noodles and started getting the more "premium" instant noodles, and holy moly, they are so much better. The one I've been eating a lot lately has 2 packets of dry stuff and 3 liquid pouches! The life of luxury."

A letter to my mother-in-law about my 3 boys.

You always stole my thunder. You gave them everything they wanted. You never said no when they asked for anything.

A second helping of dessert. Candy before dinner. A few more minutes in the bath. Money for the ice cream truck.


I struggled to show you respect and appreciation while trying to make sure you didn't spoil my children. I thought you would turn them into “selfish brats" by giving them everything they wanted. I thought they might never learn to wait, to take turns, to share, because you granted their wishes as soon as they opened their mouths and pointed.

You held each one of my babies long after they fell asleep. Didn't you understand that I needed them to learn to fall asleep on their own?

moms, mother in laws, in laws, family, kids, motherhood, relationships, love, open letter The author's three sons as young children. Tina Plantamura

You ran to them as soon as they made the tiniest sound. How would they ever learn to self-soothe?

I resented you for buying the best and most expensive gifts on their birthdays and on Christmas. How could I possibly compete with you?

And how they loved afternoons spent with you. You made their favorite things for dinner—three different meals for three different boys. And you always had a little surprise. A present, candy, or a special treat. I didn't want them to associate you with gifts and sweets. I thought they should love you for you. I tried to tell you this, but you wouldn't listen.

I spent a lot of time wondering why you did all these things and how I could get you to ease up. I know grandmothers are supposed to “spoil the kids" then send them home, but you were...ridiculous.

Until you were gone.

moms, mother in laws, in laws, family, kids, motherhood, relationships, love, open letter Grandparents often aren't appreciated fully until they're gone. Photo by Robin Noguier on Unsplash

I had to hold my boys and tell them that their grandma died. It didn't seem possible—you were supposed to be there for all the other special moments: proms, graduations, weddings. But they lost their grandma too soon and too suddenly. They were not ready to say goodbye.

During those years when I wished you'd stop spoiling them, I never thought about how much you loved them. So much that you showed it in every way possible. Your cooking. The gifts. The candy and sweets. Your presence. The way you could recount every detail of a special moment, whether it was a perfect catch in the outfield or a sweet and slightly off-key note sung at a school concert. Your grandmotherly love for them knew no bounds. Your heart poured love from every place possible—your kitchen, your pocketbook, your words, and your tireless arms.

It's pointless to dwell on regrets, but I often think about how I had it all wrong. I was so wrong in how I perceived your generosity.

My kids, now in their teens, miss you dearly. And they don't miss your gifts or your money. They miss you.

They miss running to greet you at the door and hugging you before you could step in. They miss looking up at the bleachers and seeing you, one of their biggest fans, smiling and enthralled to catch their eye. They miss talking to you and hearing your words of wisdom, encouragement and love.

If I could speak to you one more time, I would tell you that every time a precious moment steals my heart, every time I watch them arrive at a new milestone, and every time they amaze me with their perseverance, talents, or triumphs, I think of you. And I wish that they could have you back.

Come back and love them one last time, like no one else in the world but a grandmother could. Bring your sweets and surprises. Reward them with gifts for the smallest accomplishments. Painstakingly prepare their favorite meals. Take them anywhere they want to go. All and only because you love them.

Come back and see how much they've grown. Watch each boy becoming his own version of a young man. Be in awe with me as we admire how family, friendship, time, and love helped them grow so beautifully over the years.


The more I long for you to come back, though, the more I realize that in a way, you never left.

moms, mother in laws, in laws, family, kids, motherhood, relationships, love, open letter Tina Plantamura's three teenaged sons. Tina Plantamura

I understand now. I know you loved them in every way you could. I know that being their grandma gave you joy and purpose. And of course I know that you can't come back, but I do know that your love for them will always remain. Your love built them and sheltered them in ways that cannot be described. Your love is a big part of who they are and what they will become as they grow. For this, and for every treat and gift, and every time you held them too long or consoled them too much or let them stay up too late, I will always thank you.

And I will wish a million times that you could do it all again.

MIT camera can capture the speed of light

"There's nothing in the universe that looks fast to this camera."

a man holds out his arm toward a ball of light

Photographing the path of light.

A camera developed at the Massachusetts Institute of Technology can photograph a trillion frames per second (fps).

Compare that with a traditional movie camera that takes a mere 24 fps. This advancement in photographic technology has given scientists the ability to photograph the movement of the fastest thing in the Universe: light.


The actual event occurred in a nano second—that is one billionth of a second—but the camera has the ability to slow it down to twenty seconds.

For some perspective, according to New York Times writer John Markoff, "If a bullet were tracked in the same fashion moving through the same fluid, the resulting movie would last three years."

In the video below, you'll see experimental footage of light photons traveling 600-million-miles-per-hour through water:

It's impossible to directly record light, so the camera takes millions of scans to recreate each image. The process has been called "femto-photography."

According to Andreas Velten, an MIT researcher involved with the project, "There's nothing in the universe that looks fast to this camera."
