1, generally speaking, a normal person's breath is relatively symmetrical, loud and powerful. In fact, what we want to say is that we will find that the breath of normal people is relatively symmetrical, and it is precisely because of this that the voice is relatively loud and powerful. For people with mental distribution, the voice is often not as crisp as normal people, so this statement is also correct.
2. People who are physically ill have ups and downs most of the time, because their breath is asymmetrical. In fact, what we want to say is that we will find people who are physically ill in life. Many times, it is really because of the asymmetry of breath and the relative change of sound lines. In a sense, judging a person's voice can really indirectly understand his recent physical condition.
3, it has to be said that it is because of the environment, so a person's voice may also change with the state of life, judging a person's physical condition and considering it from many aspects. In fact, it has to be said that a person's voice can indirectly judge a person's physical condition. However, due to the complex and diverse living environment, it is unreasonable to judge a person's physical condition simply by voice, and the voice may change with the change of living environment, so this statement should be treated specifically.
In fact, I have to say that people can really infer each other's physical condition and potential personality through their voices, so it is precisely because of this that observant people can really understand each other's personality and physical condition through conversation.
