I often feel tired. The so-called sub-health is actually not very healthy. Although there are no obvious big problems, there are many small problems, which show that you often feel tired. Even if you get enough sleep, you will feel very tired. You always feel that you have no strength, which means that your body is weak and you are not the same as others.
Two: memory is obviously decreased. In life, some people have a strong memory, while others have a weak memory. But when your memory is ok, you suddenly feel that your memory has declined for a while and you can't remember many things. At this time, you need to be careful to see if your body has changed recently, because the sudden decline in memory must be something wrong with your body. If I have little sleep recently and often stay up late to work overtime, I must change.
Three: I often have backache. As a young man, I am not full of vigor, but I always feel tired. I often shout back pain, and my mouth hurts. At this time, your body is likely to be in a sub-health state. Even if it doesn't hurt much, it seems to be uncomfortable everywhere. This feeling is still very painful.
At present, social pressure is generally great. Don't think that being young means that capital can be desperate. We must protect our health. Health is the most important thing.
