Neil deGrasse Tyson posted a gym selfie in a muscle shirt and people  are loving it

"A physicist thirst trap is the pleasant surprise I didn't know I needed."

For most of us, National Pi Day (March 14th, of course) came and went without much fanfare. Maybe a few show-offs recited the famous 3.14 number to as many decimals as they could remember, or someone whipped up a blueberry pie in a punny homage. But if you happened to open Facebook and follow astrophysicist Neil deGrasse Tyson, you were in for a unique surprise.

First, some might ask: what is pi? In the piece, "What is Pi, and How Did it Originate" by Steven Bogart for Scientific American, he explains, "Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle's size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14."

Here's Neil on TikTok with a cute video in anticipation of Pi Day. In its description, he writes, "We're just a few days away from #PiDay. Here's a friendly reminder to share with your friends along with a few jokes to use this year:

Why should you never start talking to pi at a party? Because it just goes on forever. What did pi say to its sweetheart? You look radian today. What was Sir Isaac Newton’s favorite dessert? Apple pi."

We're just a few days away from #PiDay 🤓 Here's a friendly reminder to share with your friends along with a few jokes to use this year: 🥧 Why should you never start talking to pi at a party? Because it just goes on forever. What did pi say to its sweetheart? You look radian today. What was Sir Isaac Newton’s favorite dessert? Apple pi.


Over on Facebook on March 13th, he shared a photo of the moon, and in a separate post, a little more information and some fun recommendations about Pi. "Pi Day (3.14) Pi has a few more digits than that. But 3.14 can get you far. Wanna get your geek on? Celebrate at 1:59:26. That gets you 3.14 1:59:26, the first seven decimal places of Pi."

The next morning, around dawn Pacific Standard Time, Neil changed his profile picture to one in which he's wearing a sleeveless muscle shirt, standing in front of a mirror at what appears to be a gym. Yes, Neil gave us a gym selfie, and why wouldn’t he?

His followers seemed delighted, with the comments reflecting a balanced mix of good humor and earnest compliments. In one of the top comments, someone wrote, "A physicist thirst trap is the pleasant surprise I didn’t know I needed. You’re in fine form, sir." Yet another seemed (jokingly) threatened: "Damn bro, save some science for the rest of us."

This person disagreed that Neil was seeking validation: "I don't know why, but I just cannot make myself see this as a thirst trap. I know you weren't even meaning it in a bad way, but he is just so humble that anything like this just somehow makes him more human and accessible. Like he's having a confident day and wants to commemorate it."

A few people really honed in on how toned his muscles are. "Neil DeGuns Tyson," one person exclaimed, while another wrote, "Don't forget, he was a high school wrestler. The muscle never completely goes away."

This commenter was perhaps referring to Neil's propensity to debate: "Feelin' cute. May agitate some astrologers later. Idk."

And lastly, this person was hopeful that the photo is the start of a training montage: "Please tell us you're training for Cosmos Season 3.... we need this!"

It's safe to say that cold plunges, or several-minute-long ice baths, are having a moment. Athletes have been using them forever to recover from workouts and rigorous games (the ancient Greeks even liked it!), but at some point in recent years, cold plunging entered the zeitgeist as an everyday therapy for normal people.

Celebrities like Drake and Justin Bieber can be seen submerging themselves in frigid water on social media. Joe Rogan relentlessly evangelizes the benefits of cold plunging to his listeners. Fitness influencers all over the globe are pushing cold plunging as the key to unlocking better results.

What are the benefits of cold plunging? For starters, it reduces inflammation in muscles, which reduces soreness. It also makes you feel absolutely amazing, as the shock of the cold water causes an intense rush of adrenaline and dopamine in the body, creating a sort of natural high that can last for hours. Some experts claim that cold plunges can reduce anxiety and stress, boost metabolism, and even keep you from getting sick!

All that with very little drawbacks, the main one being that hopping neck-deep into 50 degree water is intensely uncomfortable.

New research out of Ritsumeikan University in Japan is throwing some cold water on the trend. According to the study, a good old fashioned hot bath is a better choice for more people. And more fun, too.

Researchers took a group of 10 men and had them perform high-intensity exercise. Afterwards, one group soaked in a cold tub, one in a hot tub, and one just sat in a normal room as a control.

Not long after their 20-minute soak, the men performed high jumps, and the researchers measured how high they were able to jump.

The three-part study put the men through the rotation several times, so each man had eventually tried the cold tub, hot tub, and control room.

The findings showed that the men who soaked in the hot tub performed the best in the athletic testing afterwards.

Turns out, there's a downside to constricting the blood flow to your muscles and reducing inflammation and soreness. You also block the delivery of key nutrients and rich, oxygenated blood that promotes recovery.

Mamoru Tsuyuki, a master’s student in sports and health science and author of the study, reasoned that cold plunges still have their place when someone's injured or dealing with tremendous soreness. You can see why a Major League pitcher might dunk his arm in ice immediately after a game.

But most normal people don't need to hop into an ice bath after a workout. A hot soak is a lot more comfortable and will probably do a better job of helping those muscles recover quickly. Warmth and better bloodflow will also prioritize building new muscles rather than minimizing soreness.

(It's also worth mentioning that, unlike a hot bath, cold plunging can be pretty dangerous. If the water is too cold, you risk going into shock or hypothermia.)

Overall, the scientific community is skeptical at best of the supposed amazing benefits to cold plunging. So why did it get so popular?

The fitness community has a new cold plunge every few years.

For a while, we were sure that High-Intensity Interval Training was THE answer to all your exercise woes. Then it was foam rollers that were going to unlock all of your flexibility and mobility and send your soreness packing. Same with cupping. Then it was the massage gun, the ultimate workout recovery tool. And on and on with Peloton and Bowflex and those vibrating As Seen on TV ab belts.

The truth we don't want to admit is that everybody's body is different, and what works well for one person may not work for us. That's because it's not an easy idea to sell, it's not profitable. No one wants to buy a $5,000 cold plunge set up unless they're convinced it's going to change their life.

So influencers play up the benefits. It's what they do.

Some people love cold plunging, and they have every right to enjoy it! Others find it miserable, and that's OK, too. Cold plunging has legitimate scientific benefits, but it also has drawbacks, dangers, and a whole lot of pseudo-science behind it. It's absolutely OK if you'd rather take a warm bath or soak in the hot tub after a workout.

Now you have scientific evidence in your corner next time someone tries to pressure you into an ice bath. Just say, "Nah, I'm prioritizing bloodflow and muscle recovery today. But you have fun."

"Memories not macros."

It was hard enough to find sound health advice before social media. But now, we are bombarded by conflicting information, pseudoscience, and product-pushing from influencers every time we open up Instagram or TikTok.

Just to really drive home the next level ridiculousness of it all, a mom named Caitlin Murray recited every single bit of diet, fitness and wellness advice you've no doubt heard online in one hilarious take.

Delivered with all the dryness of a Daria episode, Murray begins:

"Hey ladies. Have you been struggling to lose belly fat? Guess what? You've ruined your metabolism by not eating enough. You're not getting enough protein. Okay, you're going to need to take grams of protein and multiply it by the number of stars in the sky, and that's how much protein you're going to need in a day in order to lose weight, but you're also going to need to stay in a caloric deficit in order to lose weight. Idiot."

But of course, she quickly retorts, “you also have to live your life, okay. Memories not macros."

Also included in her “advice” is to start lifting heavy weights 3-4 times a week and stop doing cardio…while also still getting in 10,000 steps per day, “"Sounds like cardio but we don't call it that anymore." That one had me literally LOL’ing.

In essence, we need to "Get with the times," Murray says. Which is really simple: get your 10,000 steps every day, but don't exercise every day. Oh, and rest. “Otherwise your cortisol levels are going to be through the roof."

And if you’re still somehow confused by all this, don’t worry. Just comment “science” to receive Murray’s “six-week plan to get totally snatched.” Oh, and “follow for more tips."

It wasn’t long before thousands of viewers applauded Murray for her spot-on accuracy.

"You are ... hilarious! And yes, it does feel EXaCTLY like that! Thanks for reminding me that I’m not alone," one person wrote.

Another echoed, “The F’d up thing is that this was probably the most comprehensive and logical summary of all the shit on my IG feed these days. So, thank you? 🙃”

A few celebrities even chimed in. "Omg this is the funniest thing ever," Pink wrote, while model Molly Sims added, "You're PHENOMENAL."

In an interview with Good Morning America, Murray shared that her own frustrations with being exposed to so much wellness content inspired her parody.

"I've been consuming this content like it's my other job,” she told GMA. And during that time she had repeatedly come across fitness catchphrases like "snatched" and "belly fat," which are specifically targeted toward women. Shocker.

Besides offering the world some grade-A comedy, Murray hopes it also reminds people—especially women—that there are no extreme diets, pricey supplements, or quick-fix plans that can replace long term, consistent good habits. So all advice suggesting otherwise should be “taken with a grain of salt.”

But hey, at least you burned a few extra calories giving yourself a good laugh.

Friendship

Woman accidentally creates massive women's walking group by trying to avoid going to bars

"I didn't want to go to happy hours, eat and spend money all the time."

Woman accidentally creates massive women's walking group

Saving money seems to be on the top of everyone's to-do list nowadays. Whether it's because you're trying to save up for something or you're trying to get to the next paycheck with a little something still in your bank account, cutting spending is on the top of the list for many. There's also the reality that meeting new friends is difficult if you're not willing to go out and spend a little money to go where adults go to hang out.

Going to bars, out to eat or participating in activities like pickleball requires some sort of investment that can add up. This is exactly what prompted Jas, who goes by Ms. Juicyy on TikTok, to put out a public call to see if any women would like to go walking with her one evening. It was an innocent request for a little companionship while she got in a few steps and avoided spending unnecessary money.


"If you live in Vegas and you're a girl, and if you're free on either Tuesday or Wednesday nights, you should come with us. We do this thing called 'hot girl walk.' We literally just walk for about an hour and by the time you look it's been already 3 miles. I started this because i didn't want to go to happy hours, eat, and spend money all the time. I love doing those things but every now and then it's cool to just be active," Jas explains in a video promoting her accidental walking club.

The woman put out her first call for women to walk with in August 2024 and two other women showed up. By the next time the three went walking, three other women came along. The group continues to grow and now it appears to be hundreds of women walking, chatting and making new friends.

People are bringing baby strollers, pets, and evidently a friend or two when they come out to the walks. Jas shares in a recent video posted to her TikTok a seemingly unending line of women walking along a sidewalk in the dark with her caption saying, "i guess it’s safe to say we’re a walking club now 😍 thank you so much for coming! It made my whole week to meet you guys!!"


Women in the comments of the video showing the massive turn out can't seem to get enough of what the woman created just by trying to find something else to do that didn't involve spending money.

One woman writes, "That’s the only way I’d feel safe walking anywhere."

Someone else chimes in, "I just moved and have been struggling to meet people and also get outside because I work from home I'm so glad this came up on my fyp!!!"

Another person shares their excitement, saying, "OMG I love this. safety in numbers."

"I love seeing the strollers too," one person cries.

Many people that live locally were asking for details, pretty soon the weekly walk is going to turn into a group large enough to look like a parade. But it seems as if there will be no shortage of women connecting and meeting new friends. If you're in the Vegas area, you can follow her Hot Girls Walk on Instagram.
