As we all know, the means to keep healthy is nothing more than avoiding all dissolute behaviors, unpleasant and intense emotional turmoil, and long-term nervous mental fatigue; Take at least two hours of rapid physical exercise outdoors every day; Take a cold bath often and eat moderately.
If a person doesn't do some sports every day, he can't keep healthy. If all life activity programs are to maintain normal operation, the whole or as a part of the whole, where the life activity programs are located, needs to be moved. So Aristotle was right: "Life lies in movement, and the essence of life lies in movement."
The interior of the body tissue is constantly moving rapidly; The heart beats vigorously and tirelessly in the complex process of double contraction and relaxation; Every time the heart beats 28 times, it sends all the blood of the body along the veins of the body, and the lungs keep pumping air, just like a steam engine; The large intestine squirms like a bug; Body glands are always absorbing and excreting; With the pulse beating and every breath, the brain itself completes a double movement.
In this way, if people don't exercise outside-many people's lifestyles are static and lack exercise-then the static appearance of his body will form an amazing and harmful disharmony with the ongoing exercise inside. The constant movement inside the body needs the cooperation and support of some external movements. The disharmony between the inside and outside of the body mentioned above is similar to: a certain emotion stimulates our inner boiling, but we have to try our best to restrain this emotion from showing from our appearance.
Nine times out of ten our happiness depends on our health. As long as we stay healthy, everything will become the source of happiness; But without health, all external benefits-no matter what these benefits are-are no longer meaningful, and even those benefits that belong to human subjects, such as spiritual, ideological, emotional and temperament advantages, will still be greatly reduced because of illness.
From this point of view, when people meet, they should first ask about each other's health and wish each other good health, because health is really the most important thing for a person's happiness. From this, we can draw the conclusion that the biggest stupidity is to sacrifice one's health for money, promotion, knowledge, reputation, and even for sensuality and other temporary pleasures.
Therefore, we should put health first, and a happy mood is a flower that grows from a healthy body.
Therefore, health affects our happy mood and the happiness brought by happy mood. So, a happy mood depends entirely on health? In other words, is a completely healthy person necessarily an absolutely happy person? Obviously, this is not necessarily the case. Healthy people also produce melancholy temperament and depressed mood. This is another more important topic mentioned by Schopenhauer. )
