What determines the length of life?
Is it exercise, diet, or mood?
Philosophically, internal factors are the basis for changes in things, and external factors are the conditions for changes in things. Internal causes are the main ones, and internal causes determine external causes.
Therefore, the lifespan of a person is the same, and it is also determined by internal factors. External factors are secondary.
The internal factors of human beings are the genes of the body and are inherited, so the length of a person's lifespan is mainly determined by his own genes.
Of course, external conditions also work and are also very critical.
For example, high mental stress affects the body's endocrine and immune system. Injures health.
Unhealthy life and diet affects the human digestive system and cardiovascular diseases.
Live on time and regularly, go to bed early and get up early, which can improve the body's immune system. Reduce the occurrence of diseases.
The poor natural environment also affects the human respiratory system.
In short, human lifespan is mainly the human body's own genes, which is the main factor in the length of lifespan. The acquired external environment also has an impact on a person's life span.
So, the inner genes cannot be changed and cannot be controlled by themselves. We change the external environment, living environment, eating habits, and spiritual life, and we change it from these aspects.
Life and death have fate, be happy to know fate, follow your heart, and face life with your smile. This is the correct attitude towards life and the correct way to live longevity.
