How to make yourself healthier?

Self-discipline is the biggest feature that makes a person healthy. Health is a habit that should be formed at an early age. Eat three meals a day and don't stay up late at night. Be sure to sleep at ten o'clock. Staying up late is harmful to your health. That's great. Exercise for at least half an hour every day, walk fast, or run in situ. Pay attention to less oil and less salt, match meat and vegetables, and match coarse grain flour and rice is the most important. I cook by myself, don't eat outside food, especially take-away, and wear appropriate clothes in spring, summer, autumn and winter. It is wrong for some young people not to wear cotton trousers in winter, which is the most basic condition of my body!
