Give up dinner? Landmark study shows daytime eating could be the new fountain of youth.

Eating less could lead to a longer life.

Ever since Clive McCay published his landmark 1935 study that showed mice with severely restricted diets lived 33% longer, many have wondered whether caloric restriction could extend the human life span, too.

It makes for an interesting philosophical question: Would you trade the joy of eating for a longer life?

There are a few reasons why some say this type of caloric restriction could work to extend human life spans. First, larger animals tend to live longer than smaller ones because they have slower metabolic rates. When we consume fewer calories, we have less to metabolize.

Second, it’s speculated that caloric restriction reduces free radical damage in the body, slowing the aging process.

A new study out of UT Southwestern on mice has found that caloric restriction increases longevity, which isn’t exactly front-page news. However, the intriguing part is that this study found that the time of day the mice were fed had a big effect on their life spans.

Researchers found that restricting the calories mice ate by 30 to 40% increased their longevity by 10%. But mice that were fed the restrictive diet only while active at night lived 35% longer than those that ate whatever they wanted whenever they chose.

If this type of diet were adapted for a human’s biological rhythms, we’d eat low-calorie diets during the daytime. So if you’re the type that prefers breakfast over dinner, a long life could be in the cards. But if you love a four-course dinner, it may be hard to make the adjustment.

Bottom line: If the diet is found to work the same way in humans as it does for mice, when we eat will become almost as important as what we eat. It could also lead to changing the times we wake up and go to sleep. Who wants to stop eating at 3 p.m. and then go to bed hungry at 11 p.m.?

“It’s pretty clear that the timing of eating is important to get the most bang for your buck with calorie restriction,” Dr. Joseph Takahashi, Ph.D, one of the lead researchers on the study, said in a news release.

“We have discovered a new facet to caloric restriction that dramatically extends life span in our lab animals,” said Dr. Takahashi, the Loyd B. Sands Distinguished Chair in Neuroscience. “If these findings hold true in people, we might want to rethink whether we really want that midnight snack.”

The study also makes the interesting case that low body weight isn’t necessarily tied to longevity.

“This shows that at low body weight, this popular yardstick of health (body weight) is not a predictor of life span,” said Dr. Carla Green, Distinguished Scholar in Neuroscience at UT Southwestern.

Obviously, this study was performed on mice and there’s a long way to go before we can be sure that this type of drastic dieting will expand human life or doesn’t come with any dangerous side effects. But it is compelling to imagine that by simply adjusting what and when we eat we could live up to 35% longer.

That would push the life span of the average American male from 75 to 103 and female from 81 to 109.

Mom calls out unfair 'double standard' of boomer grandparents who don't help with childcare

"I love my mom dearly, but I'm surprised at how little effort she puts in."

A stressed mom and her happy, busy parents.

As far as generational stereotypes go, baby boomers (1946 to 1964) have often been accused of being a self-absorbed generation that has had no problem hoarding wealth, disregarding the environment, and prioritizing their own interests over their families. After all, they’re the generation that predominantly raised Gen X (1965 to 1980) and older millennials ('80s babies), also known as Gen Goonie, who were the least parented group of people in decades.

It’s unfair to paint an entire generation with the same brush. Still, the people who were once called the “Me Generation” are developing a reputation for being less involved in their grandchildren’s lives than their parents. The different grandparenting styles have been attributed to the fact that boomers worked longer and therefore want to enjoy their retirement. They also have more money than their parents to enjoy traveling and pursuing their hobbies. Those looking to take shots at boomers claim that they didn’t put a lot of effort into raising their kids, so why would they be any different with their grandkids?

A mother of one, who goes by TheCalmQuail on Mumsnet (a UK-based mothers' forum), made a controversial post, calling out a significant double standard when it comes to boomers. They had no problem having their parents help raise their kids, but they don’t want to extend the same courtesy to their children.

“It's come up in a few conversations with other parents recently about how little time their parents spend with their children, especially in comparison to when they were younger and at their grandparents' daily,” CalmQuail wrote. “Myself included, I avoided nursery completely when my mother went back to work because free daily childcare from a relative, and some of my happiest regular memories are spending regular one-on-one time with my Nana.”

“I realise grandparents are entitled to their own lives, but the lack of help does seem like double standards, when a large majority have seemingly had so much help themselves,” she continued.

CalmQuail added that her mother lives up the road from her but still finds excuses not to help our child or even spend time with her kid. “It often feels like she's an extra toddler, as I have to suggest stuff to tempt her to do anything together; I manage the logistics, drive her there, etc. She will be there for emergency childcare requests when possible,” she continued. At the end of her post, she asked whether she was being unreasonable for thinking that her parents should put as much effort into raising their grandchildren as they had put into raising their parents.

The verdict: 68% thought she was NOT being unreasonable, and 32% felt that she was being unreasonable. Therefore, a majority of parents on the forum believe that Baby Boomers have the same responsibility to their grandchildren as the Silent Generation (1928 to 1945) did to theirs.

Many parents on the forum have experienced similar situations with their boomer parents and have given them a little grace by acknowledging that their grandparents didn’t have many resources or retirement expectations, so they dedicated their energy to their families.

“I know this will turn into a boomer bashing thread but my experience is my parents and their friends are early retirees with a fair bit of cash and feel they’ve earnt a nice easy long comfortable retirement (they have worked hard but only the same as us except we can’t afford a nanny, cleaner etc like they did…).so they’re busy on holidays, golfing, socialising,” a commenter wrote. “My grandparents were typical of their generation—very hard working, modest life, and incredibly family orientated, they had us every holiday.”

“I don’t think my grandparents had much in the way of expectations of retirement,” another commenter added. “They retired relatively early by today’s standards, and lived far longer than they expected. There wasn’t much of a sense of ‘enjoying your retirement’ by jetting off around the world or pursuing personal hobbies - they were always there and available.”

Ultimately, there’s nothing wrong with baby boomers enjoying their retirement, but their children have a right to feel a bit miffed by the shift in grandparenting priorities. As times change, so do expectations, but why does it feel like younger people are always getting the short end of the stick when it comes to life's necessities, such as childcare and the cost of living? Unfortunately, so many younger people feel like they have to go it alone. However, kudos to the boomer grandparents who do help out with childcare, just as their parents did. As they say, it takes a village to raise a child, and these days, our villages need to be growing instead of shrinking.

Mom removed young daughter's mustache after she was bullied, sparking debate

It's an experience many girls can relate to.

Mom removes young daughter's mustache after she is bullied.

Kids can find plenty of reasons to bully one another, and for many young girls, an easy target for bullies is making fun of dark hair or peach fuzz above the upper lip.

Rather than let her daughter's 'mustache' subject her to ridicule from her classmates, mom Aubrye (@eyrbua) shared on TikTok that she decided to remove it. It's a decision that's sparked debate among other parents.

"My daughter came home from school one day crying saying kids were making fun of her mustache and asked me to 'take it off," she shared in the video's caption.

In the video, Aubrye can be seen removing her daughter's unwanted facial hair in the video while the song "Being a Girl" by Jonica plays in the background. In the caption, she explains her decision to take off the extra peach fuzz: "I reassured her that she was beautiful no matter what but if she wanted me to to take it off for her to feel better I'd do that," she writes.

She ends the caption with a closing statement to solidify the choice: "I always want my baby to feel beautiful and confident."

In the comment section, Aubrye added an update on how it made her daughter feel. "Since doing it, her confidence is through the roof, her grades have gotten better and she comes home from school happy all the time. Definitely worth seeing my little girl happy," she wrote.

Many parents were supportive of Aubrye's decision.

"Thank you for helping her instead of just telling her to suck it up."

"I would never understand mothers who refuse to let their daughters shave."

"This is how you parent correctly. My daughter came home complaining about her eyebrows saying people were making fun of her. So I cleaned them up for her," one parent shared, to which Aubrye replied, "You’re a great mama 🩷 I always want to support my daughters and help their confidence any way I can."

Others were more conflicted about it:

"I also have a small daughter but I don't know how I feel about it because okay she took her little mustache off but what's next? If they don't like something else about her, she's gonna try to keep changing for these kids. She should just learn to be a little tougher. Or maybe just go to the school directly. I don't know I feel so conflicted."

"Personally, I’d be teaching my kid to verbally and if necessary physically stand up to bullies. Teaching them that conventional beauty is fake. It’s made up. My kid should not be shaving or changing her body in ANY way. Just to accommodate someone else’s opinions of them. To me, that just teaches them to do that their whole lives. I’d rather teach my kid to clock a bully than be a doormat."

"My daughter has been bullied for the same reason! But I have taught her to always say my mustache makes me special 🥰 and it has worked for her confidence to have a cute mustache🥸."

Whether people agreed or disagreed with her decision to remove her daughter's mustache, the post resonated with many women who grew up with the same experience:

"Ok so I’m 52 and this is me. Kids use to bully me for having a mustache and unibrow. This was back in the 80s. Kid were even meaner. Thank you for hearing her. And helping her. No one helped me," one wrote.

Another shared, "I got bullied for my mustache. Didn’t shave it until an adult and only to scrape the dead skin off. Teach your kids to love themselves. They’d say 'you’re a girl, why do you have a mustache?!'"

"My mom never let me and she doesn’t know how much it affected me that she didn’t," shared one more.

The 'world's slowest experiment,' going for nearly 100 years, is still endlessly fascinating

It takes nearly a decade for one drop of this liquid to fall.

upload.wikimedia.org

John Mainstone was the custodian of the Pitch Drop Experiment for 52 years.

Because we use water all the time, most of us have an intuitive sense of how long it takes a drop of water to form and fall. More viscous liquids, like oil or shampoo or honey, drop more slowly depending on how thick they are, which can vary depending on concentration, temperature and more. If you've ever tried pouring molasses, you know why it's used as a metaphor for something moving very slowly, but we can easily see a drop of any of those liquids form and fall in a matter of seconds.

But what about the most viscous substance in the world? How long does it take to form a falling drop? A few minutes? An hour? A day?

How about somewhere between 7 and 13 years?

The Pitch Drop Experiment began in 1927 with a scientist who had a hunch. Thomas Parnell, a physicist at the University of Queensland in Australia, believed that tar pitch, which appears to be a solid and shatters like glass when hit with a hammer at room temperature, is actually a liquid. So he set up an experiment that would become the longest-running—and the world's slowest—experiment on Earth to test his hypothesis.

Parnell poured molten pitch it into a funnel shaped container, then let it settle and cool for three years. That was just to get the experiment set up so it could begin. Then he opened a hole at the bottom of the funnel to see how long it would take for the pitch to ooze through it, form a droplet, and drop from its source.

It took eight years for the first drop to fall. Nine years for the second. Those were the only two drops Parnell was alive for before he passed away in 1948.

In total, there have been nine pitch drops in the University of Queensland experiment. The first seven drops fell between 7 and 9 years apart, but when air conditioning was added to the building after the seventh drop, the amount of time between drops increased significantly. The drops in 2000 and 2014 happened approximately 13 years after the preceding one. (The funnel is set up as a demonstration with no special environmental controls, so the seasons and conditions of the building can easily affect the flow of the pitch.)

The next drop is anticipated to fall sometime in the 2020s.

pitch drop experiment, tar pitch, solid or liquid, physics, world's longest experimentThe first seven drops fell around 8 years apart. Then the building got air conditioning and the intervals changed to around 13 years.RicHard-59

Though Parnell proved his hypothesis well before the first drop even fell, the experiment continued to help scientists study and measure the viscosity of tar pitch. The thickest liquid substance in the world, pitch is estimated to be 2 million times more viscous than honey and 20 billion times the viscosity of water. No wonder it takes so ridiculously long to drop.

One of the most interesting parts of the Pitch Drop Experiment is that in the no one has ever actually witnessed one of the drops falling at the Queensland site. The drops, ironically, happen rather quickly when they do finally happen, and every time there was some odd circumstance that kept anyone from seeing them take place.

The Queensland pitch drop funnel is no longer the only one in existence, however. In 2013, Trinity College in Dublin, Ireland, managed to capture its own pitch drop on camera. You can see how it looks as if nothing is happening right up until the final seconds when it falls.

- YouTubewww.youtube.com

Today, however, with the internet and modern technology, it's likely that many people will be able to witness the next drop when it happens. The University of Queensland has set up a livestream of the Pitch Drop Experiment, which you can access here, though watching the pitch move more slowly than the naked eye can detect is about as exciting as watching paint dry.

But one day, within a matter of seconds, it will drop, hopefully with some amount of predictability as to the approximate day at least. How many people are going to be watching a livestream for years, waiting for it to happen?

PoorJohn Mainstone was the custodian of the experiment for 52 years, from 1961 to 2013. Sadly, he never got to witness any of the five drops that took place during his tenure. Neither did Parnell himself with the two that took place while he was alive.

Sometimes science is looks like an explosive chemical reaction and sometimes it's a long game of waiting and observing at the speed of nature. And when it comes to pitch dripping through a funnel, the speed of nature is about as slow as it gets.

6th grader's science experiment answers, 'Do cat buttholes touch every surface they sit on?'

A question no one knew they needed answered.

Do cat buttholes touch every surface they sit on? Science answers.

Cat owners sometimes have unique questions that even Google doesn't always have the answer to. This is probably the sole reason cat forums exist, but one kid who needed a 6th grade science project decided to skip the cat forums for answers and instead use the scientific method. Kaeden Henry, a sixth grader living in Florida, bravely pondered a question few (if any one) has been brave enough to ask: do cat buttholes touch every surface they sit on?

Since cats do whatever the heck they want, training them not to jump on kitchen counters is a feat even Hercules struggles to complete. These fierce felines don't care if you're cooking dinner or trying to get comfy in bed. If they want to sit somewhere, they're going to do it. The thought of cat butts on that expensive Serta pillow designed to feel like you're sleeping on a cloud can gross people out, but thanks to Kaeden, you no longer have to wonder if the butthole itself is also making contact.

The curious sixth grader is homeschooled and well-versed in the scientific method thanks to her mother's PhD in animal behavior with a concentration in feline behavior. And, since they own cats, the science experiment was pretty straightforward (and directly impactful).

To complete the experiment, Henry and his mom, Kerry Hyde, bought non-toxic lipstick and applied it to each of their cat's anuses. Then, the cats were given commands.

"Non-toxic lipstick was applied to their bum-bums, they were then given a series of commands (sit, wait, lie down, and jump up. Side note: Both cats have been trained since kittenhood with a variety of commands, they also know how to high-five, spin around, and speak.), they were compensated with lots of praise, pets, and their favorite treats, and the lipstick was removed with a baby wipe once we collected our data in just under 10 minutes," Hyde wrote in a Facebook post.

The results? Turns out that, no, cat buttholes do not touch every surface cats sit on. Now, let's all take a collective sigh of relief while we go over the details. Kaeden's experiment covered long-haired, short-haired, and medium-haired cats (if your cat is hairless, you better stock up on Clorox wipes just in case).

"His results and general findings: Long and medium haired cat’s buttholes made NO contact with soft or hard surfaces at all. Short haired cats made NO contact on hard surfaces. But we did see evidence of a slight smear on the soft bedding surface. Conclusion, if you have a short haired cat and they may be lying on a pile of laundry, an unmade bed, or other soft uneven surface, then their butthole MAY touch those surfaces!" Hyde shares.

Now every curious cat owner can rest easy knowing that as long as their cat has hair, their bare bottom balloon knot is not touching the majority of surfaces in their home.

The amusing experiment caught the Internet's attention. People laughed and commented, with one person writing, "This is probably the most useful information I’ve learned from a science fair project."

"Good to know!...I can now eat my sandwich left on the counter with confidence!" another writes.

Courtesy of Kerry Hyde

"A+++!!! Whew!! I am very grateful for your sciencing on this subject. My fears from walking in on my cat sitting on my laptop keyboard and subsequently being grossed out and cleaning furiously in a hyper-ocd manner have been somewhat allayed and now maybe I won’t have to use QUIIITE so many wipes." someone chimes in.

"Finally.. Someone answers the important questions!!"

Millennial shares the lies that every kid's parents told them in the '90s

"Chocolate milk comes from brown cows."

via 90sKid4lyfe/TikTok (used with permission)

90sKidforLife shares 10 lies everyone's parents told in the era.

Children believe everything their parents tell them. So when parents lie to prevent their kids to stop them from doing something dumb, the mistruth can take on a life of its own. The lie can get passed on from generation to generation until it becomes a zombie lie that has a life of its own. Justin, known as 90sKid4Lyfe on TikTok and Instagram, put together a list of 10 lies that parents told their kids in the ‘90s, and the Gen X kids in the comments thought it was spot on.

“Why was I told EVERY ONE of these?” Brittany, the most popular commenter, wrote. “I heard all of these plus the classic ‘If you keep making that face, it will get stuck like that,’” Amanda added. After just four days of being posted, it has already been seen 250,000 times.

Here are Justin’s 10 lies '90s parents told their kids:

1. "You can't drink coffee. It'll stunt your growth."

2. "If you pee in the pool, it's gonna turn blue."

3. "Chocolate milk comes from brown cows."

4. "If you eat those watermelon seeds, you'll grow a watermelon in your stomach."

5. "Don't swallow that gum. If you do, it'll take 7 years to come out."

6. "I told you we can't drive with the interior light on. ... It's illegal."

7. "Sitting that close to the TV is going to ruin your vision."

8. "If you keep cracking your knuckles, you're gonna get arthritis."

8. "You just ate, you gotta wait 30 minutes before you can swim."

10. "If you get a tattoo, you won't find a job."

Eight more lies that parents told their kids in the '90s

Justin's video was also a hit on Reddit, where many commenters had heard the same lies growing up. However, there were a few more that they remembered hearing as kids back in the day. Commenters added eight more items to his list of 10 things that parents lied to their kids about in the '90s. Here are some great ones Justin could use to create a follow-up video:

"When the ice cream man is playing music, that means he’s all sold out."

"You'll never make any money messing around with that computer."

"Dusty went to live on a farm."

"You'll go to jail if you take the mattress tag off."

"My in-laws told my husband (as a child) not to flip the light switch on and off because he would start a fire in the wall that would burn down the house."

"I was also always told that if I played with the campfire, I would wet the bed that night."

"Green potato chips are poisonous, and eating raw hot dogs gives you cancer."

"My mom told me I couldn’t put on the skin transfer tattoo that came with my chewing gum because the tattoo had drugs in it."
