Hi Mari,
I'm Ngan. How are you? Hope you are fine. Well, thanks for your letter about how to keep your body fit. To be honest, like many other children. I ate a lot of fast food, drinks, just eat, watch TV and sleep. After that, I became a bit fat and my health is not good. Because of that, I decided to keep fit and keep healthy. First, I should eat vegetables and healthy food and drinks. Then, I need to do exercises every morning. Next, I must watch less TV and also shorten the time online. Finally, I have to do those tips always. That is all my advice. I hope you will succeed.
If free, you can write me about the process you keep fit and healthy.
Best wishes,
Ngan
