Principle 2 - Understand your body: Listening to the body, to understand whether your body is in good or bad condition, is essential. This will help you improve your health. Dr. Mosaraf Ali gave the following evidence: ( 1. Psychologically and physically: A healthy person will wake up and work in an exciting mood. 2. Keeping your back straight: This sign shows that your muscles, bones, and nerves are working stably. 3. Sleep well: Every night, you can easily fall asleep and sleep very deeply. 4. Happy face: This shows that the circulatory function of your body is working smoothly. 5. Eating well: People with good health often do not feel disgusted with food or need to consume too much. They will eat with the criteria to enjoy, taste and comfort on top). If you have wrinkles or puffiness, it is not a serious problem because the aging rate of each body is affected by the genes in each family. For example, Princess Meghan and Princess Catherine are both 37 year old but have a complete opposition aging rate. This does not mean that one is less healthy than the other. * Note: Pay attention to the first signs of unbalanced health. If you are tired, sleepless or eat more / less than normal, you should see a specialist to get the best advice. (Source: Brightside)
