Some experiences may bring people to the brink of life and death, such as: **Serious accidents**: such as serious car accidents, severe injuries to the body, facing the danger of possible death in an instant, struggling between life and death; or falling from a height, in the short and terrifying moment in the air, truly feeling the strong desire for survival and the approach of death. **Sudden major illness**: such as sudden myocardial infarction, severe pulmonary embolism, etc., the body function deteriorates sharply in a short period of time, and the vital signs are extremely unstable, as if standing on the edge of the cliff of life and death, trying to fight against the god of death. **Drowning**: Struggling desperately to survive in the water, hypoxia and fear intertwined, experiencing the difficulty of breathing until close to losing consciousness, that is the ultimate test of survival instinct. **Encountering natural disasters**: like being trapped in the ruins after an earthquake, being in a dark, hypoxic, hungry, and painful environment for a long time, constantly fighting against the god of death, feeling the despair and hope that life is fragile and may end at any time. However, it should be emphasized that such extreme experiences are often accompanied by huge physical and mental trauma, and it is not recommended to actively seek experience. Life is very precious, we should cherish the present and live in a healthy and safe way.
