China marked the 70th anniversary of their victory during World War II in the only way possible: a ginormous parade.

On Sept. 3, 2015, Victory Day kicked off with a massive military parade through Beijing.

The celebration included 12,000 troops in 50 different military formations along with hundreds of fighter jets. Veterans and soldiers ranging from 20 to 102 years old participated. Parade training was apparently so intense that multiple officers reported losing 10 pounds or more.

Blue sky at night? Parade Day delight!

A parade this size takes months, sometimes even years, of preparation.

And in the case of Beijing's Victory Day parade, numerous restrictions were put in place leading up to the festivities. Hundreds of factories were shuttered, and half of the 5 million registered cars in the city were banned from driving in the main urban hub.

Say what you will about spending government resources on a giant party, but in this case, it definitely paid off.

By the day of the parade, the air quality in the city of Beijing had dramatically improved.

An average day in Beijing clocks in on the Air Pollution Index at around 160 (out of 500), which means adverse health effects for absolutely everyone (by comparison, an average day in the worst U.S. cities is said to be around 125). But by parade day, it had dropped to 17.

Grey sky at morning? Air pollution warning.

The day after the Victory Parade, cars were allowed to return to the roads — and the Air Pollution Index in parts of the city immediately returned to an unhealthy 160 out of 500.

The sky is back to looking bleak, but the future doesn't have to be. What happened before the Victory Day parade shows that a sunny change is still possible.

Air pollution is bad. Carbon emissions are bad. Cars are bad. We've all heard it before. But what we may not have realized is how much power we have to change things.

What happened in Beijing shows us — yes, how grim the situation is, but also just how easily we can change it.

By cutting back on cars and other emissions for a mere two weeks, Beijing underwent a beautiful and healthy transformation. And yet, all it took was one day of business-as-usual to bring Beijing crashing back into the danger zone.

It's something to consider the next time you get behind the wheel. We can ensure a future of blue skies if more of us walked to work, rode our bikes, or crammed onto public transportation — even just a few times a week.

Those blue skies sure look nice to me.

It takes a special type of person to become a nurse. The job requires a combination of energy, empathy, clear mind, oftentimes a strong stomach, and a cheerful attitude. And while people typically think of nursing in a clinical setting, some nurses are driven to work with the people that feel forgotten by society.

The Emperor of the Seas.

Imagine retiring early and spending the rest of your life on a cruise ship visiting exotic locations, meeting interesting people and eating delectable food. It sounds fantastic, but surely it’s a billionaire’s fantasy, right?

Not according to Angelyn Burk, 53, and her husband Richard. They’re living their best life hopping from ship to ship for around $44 a night each. The Burks have called cruise ships their home since May 2021 and have no plans to go back to their lives as landlubbers. Angelyn took her first cruise in 1992 and it changed her goals in life forever.

“Our original plan was to stay in different countries for a month at a time and eventually retire to cruise ships as we got older,” Angelyn told 7 News. But a few years back, Angelyn crunched the numbers and realized they could start much sooner than expected.

The energy in a hospital can sometimes feel overwhelming, whether you’re experiencing it as a patient, visitor or employee. However, there are a few one-of-a-kind individuals like Elaine Ahn, an operating room registered nurse in Diamond Bar, California, who thrive under this type of constant pressure.

Prior to baby formula, breastfeeding was the norm, but that doesn't mean it always worked.

As if the past handful of years weren't challenging enough, the U.S. is currently dealing with a baby formula crisis.

Due to a perfect storm of supply chain issues, product recalls, labor shortages and inflation, manufacturers are struggling to keep up with formula demand and retailers are rationing supplies. As a result, families that rely on formula are scrambling to ensure that their babies get the food they need.

Naturally, people are weighing in on the crisis, with some throwing out simplistic advice like, "Why don't you just do what people did before baby formula was invented and just breastfeed?"

That might seem logical, unless you understand how breastfeeding works and know a bit about infant mortality throughout human history.

Dr. Alicia Jeffrey-Thomas teaches you how to pee.

A pelvic floor doctor from Boston, Massachusetts, has caused a stir by explaining that something we all thought was good for our health can cause real problems. In a video that has more than 5.8 million views on TikTok, Dr. Alicia Jeffrey-Thomas says we shouldn’t go pee “just in case.”

How could this be? The moment we all learned to control our bladders we were also taught to pee before going on a car trip, sitting down to watch a movie or playing sports.

The doctor posted the video as a response to TikTok user Sidneyraz, who made a video urging people to go to the bathroom whenever they get the chance. Sidneyraz is known for posting videos about things he didn’t learn until his 30s. "If you think to yourself, 'I don't have to go,' go." SidneyRaz says in the video. It sounds like common sense but evidently, he was totally wrong, just like the rest of humanity.
