Improving quality and prolonging lifespan with sufficient clothing and food leads to external happiness, while excessive consideration leads to internal emptiness. As people age, their physiological functions gradually decline, their ability to resist diseases is insufficient, and they are gradually plagued by diseases, causing many people to feel depressed and unhappy.
The ancient poem goes: "Old age is slow in nature, and being free from illness means having a broad mind." In fact, as long as there are no distractions in the heart, forgetting about age and illness, one must be happy and forget about worries, not knowing that old age is approaching. Only in this way can one live a healthy and long life.
