People can be compared to both a thermometer and a thermostat. What’s the difference between the two? A thermometer simply measures the temperature. However, a thermostat not only measures the temperature but also responds to it. For example, when the temperature goes down in your home, a thermostat turns the heater on. Later, when the temperature goes up, the thermostat turns the heater off. In other words, a thermostat measures the temperature and does something about it.

Some people are like thermometers. When they have a problem, they just allow it to take over their lives. Other people are like thermostats. When they have a problem or difficulty, they believe that something can be done about it. They make a decision and quickly take action. So, which kind of a person would you like to be? It’s all up to you.

Have you ever dreamed about flying in the sky while you’re awake? That’s called daydreaming. But did you know you can use your imagination to get better at something? When you imagine hitting a baseball, your muscles make tiny movements, almost as if you’re really doing it. In sports, this is called mental imagery. Athletes use it to feel readier and more confident. For example, a soccer player might close their eyes and imagine kicking the ball into the goal. They see the field, the ball, and even hear the crowd. This helps their brain get used to the action.

About 90 percent of Olympic athletes in North America use mental imagery. Experts say that when you imagine an action, your brain acts like you’re really doing it. So if you imagine hitting a baseball, your brain responds almost the same as if you really hit the ball.

The goal is to make athletes feel like they have done it before. That way, they don’t feel nervous. Instead, they feel calm and ready. This helps them play better during the real game.

The human body is like a home for tiny living things called microbes. Most of them are bacteria and viruses that live in our tummy. Deep inside our bodies live so many of them!

A long time ago, humans made a deal with microbes. We give them a place to stay and food to eat. In return, they help us digest food and keep us safe from bad germs. Without them, we can’t stay healthy.

Just like we need food to live, microbes need food, too. They eat leftover food that humans can’t digest, like fiber from fruits and vegetables. But eating a lot of certain foods like meat and white rice can cause a problem for the microbes. These foods are digested almost completely before they reach the microbes, so there isn’t much left for them to eat. When they get hungry, they can’t help us as well. So, we need to take care of our little friends. That’s why we should eat more vegetables, fruits, and foods with fiber. This is good for us and our microbes!
