Experiencing the edge of life and death is a very serious and potentially dangerous behavior. It is not recommended to feel the meaning of life by deliberately pursuing such extreme experiences. However, there are some activities that allow you to feel the fragility and preciousness of life in a relatively safe environment: 1. **Skydiving**: Jumping from a height of thousands of meters, many people will feel a thrill of being close to death during the free fall and the opening of the parachute, but at the same time, their lives can be guaranteed due to proper safety measures. 2. **Deep sea diving**: Going deep into the ocean can make you feel isolated from the world, and you will also face the complex underwater environment and feel the magic of nature and life. 3. **Rock climbing or mountaineering**: Especially climbing some peaks, life seems particularly small when facing the rugged natural environment. 4. **Extreme sports**: For example, paragliding, bungee jumping, etc., these sports require extremely high concentration and courage, allowing participants to experience a high degree of adrenaline release in an instant. 5. **Volunteer service**: Participating in some natural disaster relief or volunteering in areas with limited medical conditions can give you a deeper understanding of life, especially seeing the fragility and tenacity of others. No matter which experience you choose, be sure to pay attention to safety measures and conduct it under the guidance of professionals. At the same time, understand that the meaning of life is not just about experiencing extremes, it can also be deeply experienced in daily bits and pieces.
