Sleep is rest. If you don't rest, you won't work. You should relax. Sleep time must be guaranteed. Try to take a nap. If you are tired of reading, go to bed at once, refresh yourself and fight again. The bed pillow and room temperature must be comfortable at night in order to sleep well and be in a good mood.
Heart refers to a happy mood. Be optimistic and cheerful. Don't care about anything, work hard, but don't be bound by it. Don't think this is my only chance. Actually, I can come again. If I fail or miss, I can come again. Don't be influenced by anything. Learn to adjust yourself. Feeling comfortable is directly related to prolonging life.
Ok, it means hobbies. Whether playing chess, reading, playing ball, drawing, playing the piano, etc. You should set aside special time to do what you like often, immerse yourself in hobbies and fully enjoy life. This time will bring us great relaxation, even if you just listen to the radio and watch TV. Don't say that you have no hobbies. Giving full play to our interests and specialties will bring us a comfortable mood.
Exercise is physical exercise. As the saying goes, life lies in exercise, and it does. Never say that you are retired at home. Even if young people stay at home for a long time, their physical strength will drop and they will be exhausted. So it is best to exercise every day, at least once a week. But don't go to the gym. Go to nature to exercise. Parks with green grass, birds and flowers, mountains and rivers are the best.
This is eating, sleeping, mind, health and exercise. As long as these five points are achieved, it is not difficult to live a long and healthy life. It's easy to live over 100 years old! Come on!
