When an officer calls in "10-8," it means they’re back on duty and ready for assignments. Dispatchers know they can now be sent to handle calls.

This code is often used after completing a task, returning from a break, or becoming available again. It helps keep communication clear and efficient.

If a message is unclear or missed, the code "10-9" is used to request that it be repeated. It’s a quick way to prevent misunderstandings over the radio.

Whether the issue is static, overlapping chatter, or noise in the field, this code helps ensure that important details aren’t lost.

The phrase "What’s your 20?" comes straight from this code, meaning "What’s your location?" It’s one of the most recognizable phrases in police radio.

It’s used for officer check-ins, coordinating units, or simply finding out where someone is at any given moment.

When a "10-33" is issued, it signals an urgent situation that requires all radio traffic to stop except for emergency updates.

This clears the airwaves so vital information can get through without delay, often during critical incidents.

A "10-50" reports a motor vehicle accident, from minor fender benders to serious collisions. Officers use it to request backup or other resources.

Variants of the code may specify whether injuries are involved, helping dispatchers send the right assistance quickly.

When a disabled or wrecked vehicle needs towing, officers call in a "10-51." It’s a request for a wrecker or tow truck.

This code helps keep traffic flowing safely and clears hazards from roadways after accidents or breakdowns.

"10-76" tells dispatch and other units that an officer is on the way to a location or call.

This lets everyone know that help is on the way and gives an idea of how soon assistance will arrive.

After an officer arrives at a location, "10-97" is called in to confirm they are on the scene.

This code is useful for keeping track of personnel and ensuring that backup knows exactly who is present.

For most people, recognizing and managing their emotions isn’t easy. And even if we think we know ourselves well, human emotions are a whole world waiting to be explored. From how long they typically last to how they show up in our interactions with others, science has given us fascinating insights. Join us to discover 10 surprising facts about your emotions that you probably didn’t know.

Memory is closely tied to our emotions. That’s why a perfume can make you feel something even before your conscious mind knows why. Studies show that people usually remember how they felt more than the exact words they heard or the movie they watched: The emotion lingers longer than the content itself.

Although emotions can feel like they last days, months, or even years, they actually only last about a minute and a half. That’s right! Anger, laughter, or distress typically fade after 90 seconds, unless your brain revisits the situation or memory that triggered them.

Social media gets a lot of criticism, but there’s one reassuring fact: positive emotions actually spread the fastest online. While it may sometimes feel like "hate" dominates the internet, it’s often videos showing heartwarming human connections or adorable pets that get the most likes and shares.

We often remember hurtful comments more vividly than kind words. This is often attributed to our ancestors’ need to stay alert to danger, which gave humans a natural negative emotional bias. In other words, when it comes to our own experiences, the brain tends to focus more on the negative than the positive.

Emotions are literally tied to physical sensations. Each emotion triggers an instant bodily response (which some people hide better than others). From warmth in your cheeks with embarrassment to a racing heartbeat when nervous or afraid, your body is constantly trying to tell you about how you feel.

Of course, all humans experience the same basic emotions, no matter where we live. But the facial expressions we use to show them can vary more than we realize. Anthropological studies reveal that while expressions for core emotions like joy, sadness, anger, or fear are easily recognized by everyone, subtler emotions such as surprise or disgust can look quite different across distant cultures.

Witnessing distressing events or even stressful scenes on TV can make you feel the same way. This isn’t mystical; it’s psychological. Why? The answer is that our brains tend to absorb and mimic the emotions of those around us.

Some say laughter is the best medicine, and we have to admit, they’re not wrong. Laughter really is one of the best remedies for tension. Whether in a movie, a series, a book, or real life, a good laugh helps relax the mind and melt away negative emotions.

We don’t always experience just one emotion at a time. In fact, it’s usually the opposite. This mix of emotions can make them tricky to recognize, but analyzing and understanding them can help us respond in the best way.

Recognizing emotions means understanding that they are signals from your brain about how you perceive a situation, not instructions on how to act. It’s always wiser to pause, reflect, and choose the best course of action, rather than reacting solely to the emotions that hit you in the moment.
