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.

We can all be part of the giving movement

True

We all know that small acts of kindness can turn into something big, but does that apply to something as small as a pair of socks?

Yes, it turns out. More than you might think.

A fresh pair of socks is a simple comfort easily taken for granted for most, but for individuals experiencing homelessness—they are a rare commodity. Currently, more than 500,000 people in the U.S. are experiencing homelessness on any given night. Being unstably housed—whether that’s couch surfing, living on the streets, or somewhere in between—often means rarely taking your shoes off, walking for most if not all of the day, and having little access to laundry facilities. And since shelters are not able to provide pre-worn socks due to hygienic reasons, that very basic need is still not met, even if some help is provided. That’s why socks are the #1 most requested clothing item in shelters.

When the founders of Bombas, Dave Heath and Randy Goldberg, discovered this problem, they decided to be part of the solution. Using a One Purchased = One Donated business model, Bombas helps provide not only durable, high-quality socks, but also t-shirts and underwear (the top three most requested clothing items in shelters) to those in need nationwide. These meticulously designed donation products include added features intended to offer comfort, quality, and dignity to those experiencing homelessness.

Over the years, Bombas' mission has grown into an enormous movement, with more than 75 million items donated to date and a focus on providing support and visibility to the organizations and people that empower these donations. These are the incredible individuals who are doing the hard work to support those experiencing —or at risk of—homelessness in their communities every day.

Folks like Shirley Raines, creator of Beauty 2 The Streetz. Every Saturday, Raines and her team help those experiencing homelessness on Skid Row in Los Angeles “feel human” with free makeovers, haircuts, food, gift bags and (thanks to Bombas) fresh socks. 500 pairs, every week.

Or Director of Step Forward David Pinson in Cincinnati, Ohio, who offers Bombas donations to those trying to recover from addiction. Launched in 2009, the Step Forward program encourages participation in community walking/running events in order to build confidence and discipline—two major keys to successful rehabilitation. For each marathon, runners are outfitted with special shirts, shoes—and yes, socks—to help make their goals more achievable.

Help even reaches the Front Street Clinic of Juneau, Alaska, where Casey Ploof, APRN, and David Norris, RN give out free healthcare to those experiencing homelessness. Because it rains nearly 200 days a year there, it can be very common for people to get trench foot—a very serious condition that, when left untreated, can require amputation. Casey and Dave can help treat trench foot, but without fresh, clean socks, the condition returns. Luckily, their supply is abundant thanks to Bombas. As Casey shared, “people will walk across town and then walk from the valley just to come here to get more socks.”

The Bombas Impact Report provides details on Bombas’s mission and is full of similar inspiring stories that show how the biggest acts of kindness can come from even the smallest packages. Since its inception in 2013, the company has built a network of over 3,500 Giving Partners in all 50 states, including shelters, nonprofits and community organizations dedicated to supporting our neighbors who are experiencing- or at risk- of homelessness.

Their success has proven that, yes, a simple pair of socks can be a helping hand, an important conversation starter and a link to humanity.

Dr. Daniel Mansfield and his team at the University of New South Wales in Australia have just made an incredible discovery. While studying a 3,700-year-old tablet from the ancient civilization of Babylon, they found evidence that the Babylonians were doing something astounding: trigonometry!

Most historians have credited the Greeks with creating the study of triangles' sides and angles, but this tablet presents indisputable evidence that the Babylonians were using the technique 1,500 years before the Greeks ever were.

Upworthy's weekly roundup of joy.

Holy moly—it's fall, y'all!

As pumpkin spice swoops in and we start unpacking our cozy sweaters and cute boots, we can practically taste the seasonal change in the air. Fall is filled with so many small joys—the fresh, crisp smell of apples, the beauty of the leaves as they shift from greens to yellows, oranges and reds, the way the world gets wrapped in a warm glow even as the air grows cooler.

Part of what makes the beauty of fall unique is that it's fleeting. Mother Nature puts on a vibrant show as she sheds what no longer serves her, inviting us to revel in her purposeful self-destruction. It's a gorgeous example of not only embracing change, but celebrating it.
