Recently, a reporter interviewed an old man, whose good habits kept him healthy. The old man told me that he is 96 years old and he keeps a balanced diet. He has breakfast regularly every morning and eats some fresh fruits and vegetables. He said that he never eats fast food, such as hamburgers and ice cream. He thinks it is not good for health. For many years, the most important thing that the old man insisted on was that he drank green tea every day. He believed that tea was good for his health. The old man said that he climbed mountains three or five times a week and did some farm work in the fields. He almost never catches a cold, and he is healthier than his peers.
In my opinion, if you want to keep a healthy body, you should keep a balanced diet and exercise regularly. More importantly, you should stick to it, and then you will have a long and happy life!
