Why does the smile in the photo always look like being forced to do business?
Global science
Have you ever seen yourself smiling in the picture? do you always feel a little. Odd
It seems that as soon as the photo is taken, everyone becomes a "fake smile boy / girl". The smile is always so embarrassed and polite, and looks unhappy.
Why don't we laugh as soon as we take a picture?
As soon as I took the picture, my expression changed to "."
As early as the 19th century, the French neuroscientist Guillaume Guillaume Duchenne studied this problem.
All the changes in expression on our faces are actually the contraction and stretching of facial muscles. The question du Xing wants to explore is: when we really laugh, which muscles on our faces move?
He found that when we have a real smile, there are two muscles on the face that play an important role: the zygomatic major and the orbicularis oculi.

The zygomatic major muscles are located in the cheeks and will pull up the corners of your mouth when you smile. The orbicularis oculi muscle is the muscle around the eyes, which makes you squint your eyes when you smile and squeeze out the crow's feet in the corners of your eyes.
Such a sincere smile is also known as "Duxing smile". Its key point is that when smiling, not only the corners of the mouth, but also the eyes will move. When we take pictures, we often only look a little strange when the corners of our mouths rise.
The eyes are the key to real laughter, which is also recognized by AI.
It turns out that there is a big difference in muscle contraction between a real smile and a fake smile. And the most obvious are the muscles around the eyes.
In a real smile, the muscles around the eyes move 10% more than a fake smile.
The root cause of the difference between a real smile and a fake smile lies in our emotions. After all, most of us who show du Xing's smile are really happy and in a good mood, which activates the area of the brain responsible for dealing with emotions.
The study found that when you fake a smile, the pathway of activity on the left side of the brain is significantly different from that of a real smile. Different brain activities lead to different muscle activities, which in turn produce different facial expressions.

When you take a picture, saying "eggplant" or "cheese" may just help you mobilize your muscles, but a sincere du Xing smile may be more complicated. The easiest way to really smile in front of the camera may be to think of something happy and feel happy from the bottom of your heart.
A smile from the heart is also easy to infect people. Hey.
For many years, people have claimed that showing a "Duxing smile" in the picture may be a gift, and a good-looking fake smile seems to be a skill that varies from person to person. However, research over the past few years seems to refute this view: with a little practice, even a fake smile, you can look good-looking and sincere.
In the study, 24% of participants were able to show a "du Xing smile" even if they heard less happy news (31% from the bottom of their heart).
And when the researchers asked these people to imitate du Xing's smile, 71% succeeded.
Those who can smile well also say that they will reflect on the expressions in their daily life and often practice making "fake smiles" in their daily lives. In other words, as long as we practice consciously, we can smile more naturally in the picture.
But if you are in a bad mood, no matter how you laugh, it may not be true. Another study found that it is difficult to fake a "Duxing smile" when a person is in a bad mood or under a lot of stress.

However, we don't always laugh when we are happy. There is also a kind of smile that is really forced to smile. This kind of smile can appear in situations of fear and embarrassment.
The most classic is "fake smile Boy" Gavin Thomas. He smiled with fear and bewilderment when his uncle put a lizard on his head.
I was scared, but smiled.
The smile of fear is probably handed down from our ancestors. The researchers cite rhesus monkeys as an example. When they show their teeth, it means being nice, a way to defuse tension and avoid being attacked by more powerful monkeys.
On the other hand, when we are in danger, smiling means "unwilling to admit the truth", which is like a signal of self-deception.
In a word, when you are happy, the smile will come out naturally. Learn to pretend that du Xing smiles only to appear more sincere in the picture. Smiling far-fetched often may lead to emotional fatigue, so there is no need to pretend to smile when you are unhappy.
As mentioned above, smiling means "unwillingness to admit the truth". For example, there is only one day left for two days off (smile)

Davos 2026: The Last-Chance Saloon to Save the Old World Order?
Every January, the Swiss town of Davos becomes a temporary capital for the world’s elite. Politicians, CEOs, bankers, and thought leaders converge on the snowy Alps for the World Economic Forum (WEF), a gathering that blends diplomacy, business strategy, and high-profile networking. But in 2026, Davos carries an unusually heavy weight: many are asking whether this year’s forum is the last-chance saloon to preserve the old world order. The “old world order” refers to the system of global governance, trade, and alliances dominated by Western powers since the end of World War II. It’s a framework built on liberal democracy, free markets, and institutions like the United Nations, NATO, and the International Monetary Fund. But cracks have been appearing for years—rising nationalism, economic inequality, technological disruption, and the ascent of new global powers are challenging the old guard. Davos 2026 may be where these challenges are addressed—or exposed. A Gathering of Uneasy Allies Davos has always been more than a conference; it’s a stage. World leaders like the U.S. president, Chinese premier, and European Union officials attend alongside CEOs of tech giants, investment banks, and energy conglomerates. In past years, it has been a place for deal-making, policy announcements, and networking in an environment removed from daily political pressures. This year, however, the tone is tense. With geopolitical rivalries intensifying—from U.S.-China competition to ongoing conflicts in Eastern Europe—the forum is less about optimism and more about survival. Many attendees see it as a final opportunity to steer global institutions in a way that sustains stability, economic growth, and cooperation in a rapidly shifting world. As one European diplomat reportedly told journalists: “We’re past casual discussion. This is about whether the rules of the game we’ve known for decades can continue to function.” Economic Uncertainty and the Quest for Stability The global economy is at a crossroads. Inflation, supply chain disruptions, and debt crises have put pressure on governments and corporations alike. Davos provides a platform to coordinate strategies, whether that’s stabilizing financial markets, agreeing on new trade frameworks, or tackling climate and energy crises. But the challenge is bigger than economics alone. The rise of digital currencies, artificial intelligence, and global tech conglomerates has shifted the balance of power. Traditional Western institutions are struggling to keep pace with these innovations, while emerging economies leverage technology and alternative governance models to increase their influence. In this context, Davos 2026 is not just about discussion—it’s about defining who sets the rules for the next era. The Climate Crisis as a Litmus Test One area where the old world order faces a major test is climate policy. Despite decades of conferences and commitments, global emissions continue to rise. The forum’s agenda includes discussions on renewable energy investment, carbon taxation, and sustainable finance—yet the real question is whether collective action can overcome national self-interest. For some attendees, climate is more than an environmental issue; it’s a proxy for global governance. Nations that fail to cooperate on climate risk destabilizing trade, migration, and economic security. Davos 2026 may reveal whether the old mechanisms for multilateral cooperation can still work—or whether the world is moving toward fragmented blocs of competing interests. The Rise of New Powers Another key dynamic is the shifting balance of global power. Emerging economies in Asia, Africa, and Latin America are asserting themselves politically, economically, and technologically. Countries like China, India, and Brazil are shaping new trade and financial networks, sometimes outside traditional Western-dominated institutions. This diversification of influence poses a challenge for Davos. While the forum has historically been Western-centric, ignoring emerging voices could make its conclusions irrelevant. In 2026, the question is whether the WEF can integrate new powers into a cooperative framework—or whether the old world order will crumble under the weight of its exclusivity. Technology, AI, and the Future of Governance Technology is another frontier where the old world order is on trial. Artificial intelligence, cyber warfare, and digital surveillance are reshaping economies and politics alike. CEOs and policymakers in Davos 2026 are expected to discuss regulatory frameworks, ethical AI use, and cybersecurity collaboration. The stakes are high: how nations and corporations govern technology today could determine whether global systems remain stable or fracture. If the old world order fails to set rules for emerging tech, alternative models led by new powers could take hold, redefining global norms. Why Davos 2026 Feels Like a “Last-Chance Saloon” The term “last-chance saloon” evokes urgency. For decades, the old world order relied on cooperation, multilateralism, and shared values to maintain relative peace and prosperity. Today, cracks are visible: rising populism, regional conflicts, economic nationalism, and technological disruption all threaten the status quo. Davos 2026 is unique because it isn’t just a forum for ideas—it’s a test of relevance for the institutions themselves. Leaders will attempt to negotiate solutions, but the outcomes may reveal whether the old structures are adaptable—or obsolete. What to Watch Some of the key signals to watch at Davos 2026 include: Trade agreements and economic cooperation: Will major powers commit to joint frameworks or pursue protectionist policies? Climate action pledges: Are countries willing to act collectively, or do national priorities dominate? Technological governance: Will there be consensus on AI, cybersecurity, and digital currency regulations? Representation of emerging powers: Are new voices integrated into the conversation, or marginalized? The answers could indicate whether the forum reinforces the old order—or marks its final chapter. Final Thoughts Davos 2026 is more than a gathering of the global elite; it’s a litmus test for the old world order. The forum’s success—or failure—may determine whether multilateralism, cooperation, and shared governance survive in an era of rising nationalism, technological disruption, and shifting power dynamics. For observers, policymakers, and citizens alike, the stakes couldn’t be higher. The snowy streets of Davos may once again host ambitious speeches, networking dinners, and visionary panels—but the real question remains: can the old world order be saved, or is it time to prepare for a new world entirely?

So You Decided To Become a Nurse Practitioner:
So you decided to become an "Advanced Practice" nurse. Congratulations!... is what I would say if this was a good idea. Grad school? In this economy? What were you thinking? Likely it was something along the lines of either 1) “I've seen these other chucklefucks do it— Why can't I?” or even 2) “I've got a nice career, I should shake it up. I miss feeling like I have no clue what I'm doing.”
