Zhuge Liang recited a poem after waking up, including one sentence, "Spring sleep in the thatched cottage is enough." It can be seen that he pays great attention to sleep and health preservation, and his physical fitness is still good.
One third of a person's life is spent in sleep. Adequate and good sleep is the most basic and important way to keep fit. Through adequate sleep, the brain can get enough rest, eliminate fatigue, restore spirit and physical strength, which is conducive to improving work and study efficiency. Adequate and sound sleep is also conducive to the synthesis of protein in the body and the memory storage of information. In addition, physiological changes such as decreased breathing, decreased heart rate, decreased blood pressure and decreased body temperature during sleep contribute to the harmonious health of internal organs, thus prolonging life.
But Zhuge Liang's life span is not long, only 54 years old. Why? In short, it was because he came out to help Liu Bei fight for the country, was tired for a long time, and died of heart and lung failure. Especially after Liu Bei's death, in order to help orphans, he often "stayed out at night, did everything himself, and didn't have enough to eat every day". For the benefit of the country, he gave up his personal sleep, diet and health care and the combination of work and rest.
Cao Cao, a contemporary of Zhuge Liang, was not only a politician and strategist, but also a poet and health worker. He always believed that he was a hero. In an interview with Liu Bei, the hero in the Romance of the Three Kingdoms, he said: "Heroes have ambitions, good plans in their stomachs, opportunities to hide the universe, and ambitions to swallow the world."
He also said to Bei: "The heroes in the world today are the ears of the monarch and the minister!" Throughout Cao Cao's military career, he loved talents and avoided talents, including killing innocent and unjust people, destroying the talents of seventeen kings, unifying the talents of the north, and being optimistic and heroic. Mao Zedong appreciated the poem written by Cao Cao at the age of 53: "Although a turtle has a long life, it will turn to dust even though it is still foggy with snakes. The old horse is nowhere in sight, aiming for thousands of miles; In the twilight of the martyr's life, his heart is strong. The period of profit is not just in the sky; You can live happily for a long time. "
The meaning of this poem by Cao Cao is: "The tortoise" has a long life, but it will eventually die; "Teng snake" can soar on the clouds and eventually turn into dust. Although a swift horse lies in the stable, its ambition is still galloping on the battlefield; Although the hero is old, he will continue to struggle. The length of life is not simply determined by innate factors; Paying attention to health care, optimistic life and physical exercise the day after tomorrow can prolong life. At the age of 65, Cao Cao lived a positive and optimistic life, which was regarded as longevity in the troubled times at the end of the Eastern Han Dynasty, which was inseparable from his concept of health preservation.
