Do you know what makes a song popular? Music experts found that repetition is one reason. People love songs with repeating melodies and lyrics.

The researchers studied popular songs. They found that the top ten songs had more repetition than other songs. A good example is the song “Baby Shark.” It is one of the most famous children’s songs. It goes like this: “Baby shark, doo doo doo doo doo doo. Baby shark, doo doo doo doo doo doo.” As you can see, “doo doo” repeats many times.

Why do people love songs with repetition? These songs are easy to understand. The repeated parts help people remember them. This makes the songs fun to listen to!

For teens like you, looking in a mirror is a daily routine. You probably think “I’m too short!” or “I’m too fat!” The more you look, the more flaws you notice. But you are not alone. Many people also have a hard time accepting their bodies. If you only think about what you don’t like, you might start to hate yourself. So, don’t be so hard on yourself.

Here are some things that can help you feel better. First, accept your body as it is. Nobody is perfect, and you don’t have to be perfect, either. You just need to be yourself. In addition, find things to like about yourself. They can be your hair, your hands, or even your smile. Finally, remember that nobody is like you. You are one of a kind, and that’s what makes you special.

Dolphins breathe in a different way than fish. Fish take oxygen from the water. They don’t need to breathe air. But dolphins are mammals, just like us. This means dolphins need to breathe air from above the water. They go to the surface every few minutes to take a breath. If dolphins slept like humans, they could drown.

How can dolphins sleep and still breathe? Nature helps them with this! A dolphin’s brain has two parts, like a human’s brain. But dolphins can’t sleep completely like we do. When they sleep, they turn off one part of their brain. The other part stays awake. After about two hours, the parts switch. They take turns staying awake, so each part gets about four hours of sleep. This way, dolphins can have eight hours of sleep in a day!
