As the ancient saying goes: speak a thousand words without harming oneself.
When I was young, I didn't take it seriously and often argued with people about a certain viewpoint or matter.
It wasn't until I exhausted myself and almost fell ill with anger that I realized: talking too much is wasting myself.
Too much speech leads to fatigue, and fatigue can harm the body.
In this lifetime, controlling one's mouth and speaking less is the best way to maintain good health.
