Health 21 is like a plan that helps people stay healthy. It's like making a list of things you need to do to stay healthy. Just like you make a list of things to do when you wake up in the morning, Health 21 is a list of things people need to do to stay healthy.
It tells us that we need to eat healthy food, drink lots of water, and exercise regularly. It also tells us that we need to get enough sleep and avoid things that can harm our health, like smoking or drinking too much alcohol.
Health 21 is like a very long list of things we need to do to take care of our bodies so we can grow up strong and healthy. Just like how mom and dad tell you to eat your vegetables and go to bed early, Health 21 is telling everyone the same thing. It's important to listen to Health 21 so we can stay healthy and happy!
