If you're at the airport

Good news for fitness-loving travelers: Yoga rooms are popping up in airports worldwide—as are walking paths, pools, and gyms. In fact, some of the most-traveled airports (including Chicago O’Hare, Dallas Fort Worth, San Francisco, Dubai International, and Singapore Changi) boast fitness amenities. Visit airportgyms.com to learn more about what's available at airport you'll be in.

If you're in your hotel room

Beyond the hotel gym, you’ll find in-room workout tools and videos, loaner gear for those who’d rather not pack (or forgot!) their own, and exciting group classes. Some fitness-friendly chains: Westin, Omni, Even, Fairmont, Sheraton, Kimpton, Standard, and Hyatt Place. And if you're not staying at one of these hotels, you can still do simple 5-minute workouts for your lower body and upper body right in your room.

The image revealed a mass on her right lung that turned out to be a malignant tumor. Rivas was 32 and had never smoked a cigarette in her life. "I want people to know lung cancer can happen to anyone," she says.

Rivas has joined the American Lung Association's Lung Force campaign, to spread the word that her disease isn't just a smoker's affliction. "It's true that the majority of people with lung cancer have some history of tobacco use," says ALA spokesperson Andrea McKee, MD, the chair of radiation oncology at Lahey Hospital Medical Center in Burlington, Massachusetts. "Having said that, 15% of patients diagnosed with lung cancer have no history of tobacco use—and they may be quite young."

Other known risk factors aside from smoking include a family history of the disease, as well as exposure to certain air pollutants, such as asbestos, arsenic, radon, even diesel fumes, says Dr. McKee. Lung cancer is the most common cancer worldwide; and each year, it kills more women than breast, ovarian, and uterine cancer combined.

If it's diagnosed early, the disease is actually highly curable, Dr. McKee says. Luckily this was the case for Rivas. She had her tumor removed in 2013, and is now thriving. (She ran a half-marathon last year!)

But only about 16% of cases are caught at stage 1. "Usually it’s like a 7- to 8-millimeter nodule sitting in the middle of a lung that doesn’t have any symptoms associated with it," says Dr. McKee. Most patients are diagnosed later, once the tumor has grown large enough that it's "pushing on an airway, resulting in some breathing problems," she explains.

That's what Marlo Palacio experienced just before the holidays in 2013, when she developed a cough unlike any cough she'd ever had before. "I would feel like I was out of breath or gagging," she says. At first, the social worker from Pasadena, California, assumed she'd picked up a bug from her toddler son. But six weeks later, the cough hadn't gone away. Doctors diagnosed Palacio—an otherwise healthy, 39-year-old non-smoker—with stage 4 lung cancer. 

At stage 4, lung symptoms like Palacio had (and others such as pneumonia and coughing up blood) may be accompanied by problems elsewhere in the body, such as back pain, bone pain, headaches, weight loss, and confusion, says Dr…

Week 1: ID your guilt triggers

“If you can learn to pause and recognize when you feel guilt coming on, you’re halfway toward fixing the problem,” says Whitbourne. So right off the bat, get to the bottom of what makes you feel the most remorse. 

Pay attention: Notice any moments you feel guilty, as well as what prompted the pangs (you missed a deadline, you spent a lot of money). It may help to take some notes, either on paper or in your smartphone. 

Check the frequency: Did you get ticked at yourself each time you bought a $15 lunch this week? Do you lie in bed every night wishing you’d been more patient with your kids? Track how often specific subjects leave you regretful. 

Group the majors and minors: At the end of the week, pinpoint the issues that incited guilt more than once or weighed on you more heavily than others. (You’ll deal with the lesser regrets in week three.)

Week 2: Change your perspective

"You don’t want to try to just be ‘over’ a guilt that’s coming up a lot for you," says Whitbourne. "Pull it out, look at it and come up with some alternative interpretations."

Envision a redo: Think (or even talk out loud) about what you wish you were doing differently—maybe you want to have a better attitude at work, or you think you should reel in your spending by creating a budget. “It doesn’t mean you have to go out and make some drastic change right this minute, but you’re talking about it, and that’s productive,” says Susie Moore, a life coach in New York City and the author of What If It Does Work Out?. 

Pick a different emotion: "Guilt and sadness and anxiety are all on a continuum in a way,” says Whitbourne. “And when we’re stressed, it’s easy to be self-critical." Try asking, "Wait, does it really make sense to be feeling guilty at this moment? Or am I letting stress get to me?” 

Realize you’re human: "Perfectionism is often what drives guilt," says Whitbourne. "At some point, you have to just accept your limitations." Moore adds that it can even help to tell yourself, "No mom or wife or employee is doing everything flawlessly."

Week 3: Shake off the small stuff

"To say you will never feel guilty again about something silly would be ridiculous," says Whitbourne…

While we hope the marathoners feel better than that on Sunday morning, we’ll admit it: We’ve been there.

The video, from the American Chemical Society, goes on to explain the science behind why we “bonk,” “hit the wall,” or, if we’re lucky, catch the drug-like runner’s high. (Hint: It’s got a lot to do with proper training.)

If you’ve ever wondered why it’s important to carbo-load, what that burning feeling in your legs really means, why you sweat so much, and whether you can drink too much water, the answers are here.

In places like Kenya or India, amputations are often the result of more commonplace and unfortunate incidents, like automobile accidents or train mishaps involving businesspeople on their commutes to work.

Each year, tens of thousands of people in low-income nations suffer amputations, explained Dr. Krista Donaldson, CEO of medical device non-profit D-Rev, at Fortune’s Brainstorm Health conference in San Diego Wednesday.

Modern prosthetic limbs are often expensive, she said, with some devices costing upward of $1,000, making it hard for struggling medical clinics to afford them. And even when those devices are donated to clinics operating in impoverished nations, frequently those devices go unused, and the clinics are unable to perform the maintenance required to keep them functional.

“Most medical devices are designed for places like here, not low-income clinics,” Donaldson said in reference to clinics in wealthy nations that can more easily afford and maintain the prosthetics. D-Rev created more affordable prosthetic limbs to help amputees worldwide who don’t have access to the medical devices.

For instance, Donaldson showed off a recently developed artificial knee that costs $80 and contains the organization’s custom technology such as an embedded spring that helps amputees move the artificial leg forward as they walk.

The artificial knee was also designed to accommodate uneven terrain and rocky roads, unlike other devices built with smoother, paved surfaces in mind.

Currently, the knee is being used in 17 countries, but she hopes to bring it many more nations over the next three-to-five years.

Although I don't play around with makeup in that same way (zero fake blood in my everyday makeup routine, sigh) I still love watching special-FX makeup artists on YouTube transform themselves or others.

Any of these videos that need to move or drastically change the brows usually did so with some sort of brow cover-up that included a glue stick or spirit gum or wax, all of which sounded like really fun ways to lose half your eyebrow hairs when trying to take it all off. But I came across a few that used soap to replace glue, which would make clean-up a million times easier because your cleanser is right there on your face, waiting for you. But that trick didn't have any real-life application for me.

Then I saw one of my favorite makeup artists on YouTube use soap to style her brows for a normal makeup look. 

MIND. BLOWN.

So, obviously, I had to try it.

First, I tried it the special-FX makeup way. All you have to do is take a humble bar of soap, dampen it a bit so it's not dripping but wet enough to move, and apply it lightly to the brows.

Since the goal isn't to erase my brows completely, this really didn't work because it applied way too much soap and just gave a crazy white cast to my brows and felt really heavy and gross.

Don't do that.

Instead, take the eyebrow brush of your choice, wet it, and scrub it all up in that soap.

With enough suds on the brush, you can easily brush it through your brow hairs. I typically don't style my brows upwards like this, but it was really hard for you to see the effect any other way.

When you inevitably have soap all over your brows, lightly press with a tissue to remove the excess bubbles while keeping the soap stuck in your brow hairs.

From there, you can let your brows dry and apply any brow powder/pomade/pencil of your choosing, I would just stay away from brow-gel-type products so it doesn't get all gummed up with the soap.

So did this work? Yeah, totally. It took maybe a minute or two per brow, and my brows stayed up and perky for a good six hours or so. Honestly though, my usual brow routine of powder and maybe hairspray on a spoolie lasts longer than this.

It all comes down to the soap you choose. The Dove bar I've been using has a lot of moisturizing agents included to make your skin much happier. A better choice would be a harder, less moisturizing soap. The fats and oils that give real soap that almost waxy feeling would give significantly better results in holding your brow hairs in place.

Now my question is, can this same technique be used for taming baby hairs and flyaways? We shall see.
