First of all, our ancestors said
Although modern people's knowledge level is generally higher than in the past, people's research on knowledge in the past was better than now. Take the old saying, "Old people don't drain residual sperm, and young people don't eat fierce fire". What does this sentence mean? The ancients knew it even if they didn't read any books, but many modern people didn't know it.
Literally, some people will misinterpret this sentence as an exhortation to men. In fact, it is a word about health preservation, which applies to everyone. Moreover, this sentence was summed up by our ancestors. If you want to be healthy, you must listen to the advice of your ancestors.
Second, the way of keeping in good health.
Since this sentence is about health, it is better to discuss health first. I don't know if you have noticed that the daily life of the elderly is to go to bed early and get up early, and have three meals regularly. Although the diet is very different, the daily routine is very fixed. Especially in the hometown of longevity, everyone has their own way of keeping in good health. For the moment, in fact, it is the elderly who pay the most attention to health.
Middle-aged people are busy with their lives, while young people are addicted to staying up late and their work and rest are upside down. The old people are the ones who cherish life the most now. In fact, health care seems to be very particular, in fact, it is to let people live a healthy life. The picture of Lycium barbarum in beer is just psychological comfort. The old saying "don't drain the residual essence, eat less and strengthen the body" is telling people how to keep fit. Health preservation does not mean that although it does not mean longevity, it will definitely make people healthier.
Third, "Old people don't drain residual essence, and they don't eat strong fire."
The life span of ancient people was much shorter than that of modern people. In order to live longer, ancient people paid great attention to health preservation. The "essence" in the first half of the sentence "an old friend does not abandon the residual essence" refers to essence, which has two main meanings here: the first layer is male, and people should know how to restrain their desires; This second layer is also the most important, referring to the human spirit.
Walking in the street, you will find that although people come and go, everyone's spirit is completely different. Some geniuses are full of pride, while others are sad. People should worry less, be optimistic and positive, and ignore what can be ignored. When you get older, you will enjoy your old age, so that your mental state will be better and your body will be more comfortable.
The second half of the sentence "eat less and be strong" says that you can't blindly take supplements during adolescence. Some people go to the hospital when they are sick, which is a trivial matter. People are stronger and have more firepower when they are young. Sometimes it's normal to feel a little uncomfortable, but tonic will make people feel better soon.
This situation will lead to overcompensation, and nothing will become anything. "Don't give up your essence when you are old, and don't eat fierce fire when you are young", which means that you should recharge your batteries when you are old, don't spend too much energy, and don't eat some food that is harmful to your health when you are young. This regimen seems simple, but it is the basis of adjustment.
At the same time, there is also a saying that "inaccessible places have insufficient yang and abundant yin". This sentence means that the place where you live will also have an impact on people's health. An empty house that is uninhabited all the year round always looks gloomy. When people choose an address, they'd better choose one with good air circulation and sufficient light.
label
Everything the ancients said was summed up through the dribs and drabs of life, and the causal relationship of some things has been thoroughly seen. Health preservation is also nourishing qi. "Don't drain residual sperm when you are old, and don't eat strong fire when you are young" is a sentence that tells people to fundamentally adjust. If I can do this, I think there will be much less distress in my life, and I will be naturally comfortable, physically and mentally happy and healthy.
