Boys and girls, how is your body? Now let's imagine that your body is like a big f1. It takes in "materials" and puts out "goods". If you use better materials, your goods will come out much better.
What does this mean in real life? It means g2 the right amount of sleep, eating food that is good for you, and e3 more often. You might not think about this much as a young student, but please believe in me that it becomes much more i4 as you get older.
It is very good to start b5 a better "factory" at a young age. Getting into the habit of living healthily can help you a lot in many ways. If you get enough sleep, you will be able to focus better on your studies. Eating h6 food helps your body grow s7 and fight off sickness. And exercise can help you stay f8 both physically and mentally.
This sounds like a lot to do. So start small—try to go to bed at the same time each night and w9 up at the same time as well. Find time to eat a single apple each day—people often say "an apple a day keeps the d10 away". Try to exercise each day, even if it's only for 10 minutes. Doing these little things will help you build a great "factory".
