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

Breakfast people are happy.

diet, longevity, caloric restriction

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.

Finally, someone explains why we all need subtitles

It seems everyone needs subtitles nowadays in order to "hear" the television. This is something that has become more common over the past decade and it's caused people to question if their hearing is going bad or if perhaps actors have gotten lazy with enunciation.

So if you've been wondering if it's just you who needs subtitles in order to watch the latest marathon-worthy show, worry no more. Vox video producer Edward Vega interviewed dialogue editor Austin Olivia Kendrick to get to the bottom of why we can't seem to make out what the actors are saying anymore. It turns out it's technology's fault, and to get to how we got here, Vega and Kendrick took us back in time.

They first explained that way back when movies were first moving from silent film to spoken dialogue, actors had to enunciate and project loudly while speaking directly into a large microphone. If they spoke and moved like actors do today, it would sound almost as if someone were giving a drive-by soliloquy while circling the block. You'd only hear every other sentence or two.

Man hailed 'Highway Hero' for running across four lanes of traffic

Holy cow, Bat Man! You're always supposed to be aware of other vehicles when you're driving but what do you do when you notice someone has lost consciousness while speeding down the highway?

It's a scenario that no one wants to see play out, but for Adolfo Molina, the scenario became reality and he didn't hesitate to spring into action. Molina was driving down the highway when he spotted a woman in a blue car who lost consciousness as her car careened down the shoulder of the highway. The concerned driver quickly pulled over in order to attempt to rescue the woman.

But there was a problem, he had to cross four lanes of traffic on the highway just to make it to the woman's still moving car. That obstacle didn't stop him. Molina sprinted across the highway, crossing right in front of a black pick up truck before running at full speed to attempt to open the woman's door and stop her car.

Pennsylvania home is the entrance to a cave that’s been closed for 70 years

You can only access the cave from the basement of the home and it’s open for business.

This Pennsylvania home is the entrance to a cave.

Have you ever seen something in a movie or online and thought, "That's totally fake," only to find out it's absolutely a real thing? That's sort of how this house in Pennsylvania comes across. It just seems too fantastical to be real, and yet somehow it actually exists.

The home sits between Greencastle and Mercersburg, Pennsylvania, and houses a pretty unique public secret. There's a cave in the basement. Not a man cave or a basement that makes you feel like you're in a cave, but an actual cave that you can't get to unless you go through the house.

Turns out the cave was discovered in the 1830s on the land of John Coffey, according to Uncovering PA, but the story of how it was found is unclear. People would climb down into the cave to explore occasionally until the land was leased about 100 years later and a small structure was built over the cave opening.

Relationship expert tells people to never get married unless you're willing to do 3 things

"If you and your partner (both) are unable or unwilling to do these 3 things consistently forever, you won’t make it."

Relationship expert gives people advice on getting married.

Being in a relationship can be difficult at times. Learning someone else's quirks, boundaries, and deep views on the world can be eye-opening and hard. But usually, the happy chemicals released in our brain when we love someone can cause us to overlook things in order to keep the peace.

Jayson Gaddis, a relationship expert, took to Twitter to rip off people's rose-colored glasses and tell them to forego marriage. Honestly, with the divorce rate in this country being as high as it is, he probably could've stopped his tweet right there. Don't get married, the end. Many people would've probably related and not questioned the bold statement, but thankfully he followed up with three things you must be willing to do before going to the chapel.

Before going into his reasons for why he tells people not to get married, Gaddis explained that he is a person that "LOVEs being married." I mean, it would probably make him a pretty weird relationship expert if he hated relationships, so it's probably a good thing he enjoys being married. Surely his spouse appreciates his stance as well.

Humanitarian Helen Keller circa 1920.

In a 1954 documentary short, humanitarian Helen Keller expressed that her greatest regret in life was being unable to speak clearly. But given that she could not see or hear, her speech was quite remarkable.

Keller was born in 1880 and, at the age of 18 months, contracted an unknown illness that left her deaf and blind. But with the help of her teacher, Anne Sullivan, she was able to overcome her disabilities and become an outspoken advocate for the voiceless and oppressed.

10 years ago, a 'Stairway to Heaven' performance brought Led Zeppelin's surviving members to tears

Heart, John Bonham's son and a full choir came together for the epic tribute.

Led Zeppelin got to see their iconic hit performed for them.

When Billboard and Rolling Stone pull together their "Best Songs of All Time" lists, there are some tunes you know for sure will be included. Led Zeppelin's "Stairway to Heaven" is most definitely one of them.

It has everything—the beauty of a ballad, the grunginess of a rock song, the simple solo voice, and the band in full force. "Stairway to Heaven" takes us on a musical journey, and even people who aren't necessarily giant Led Zeppelin or classic rock fans can't help but nod or sing along to it.

Of course, it's also been so ubiquitous (or overplayed, as some would claim) to become a meme among musicians. Signs saying "No Stairway to Heaven" in guitar stores point to how sick of the song many guitarists get, and when Oregon radio station KBOO told listeners they would never play the song again if someone pledged $10,000, Led Zepelin singer Robert Plant himself called in and gave the donation.
