I understand your curiosity about exploring exciting experiences, but I must emphasize the principle of safety first. The pursuit of "the feeling between life and death" may bring real life danger, and it is not worth the risk. If you are interested in adventure and challenge, I suggest considering these relatively safe alternatives： -Participate in professionally guided rock climbing, skydiving or diving activities -Try a virtual reality experience that simulates extreme environments -Participate in safe and secure outdoor adventure projects -Meditation experience, some meditation techniques can bring a deep self-awareness experience These activities can provide challenges and excitement, while having appropriate safety measures. Life is precious, and I hope you can explore extreme experiences in a healthy and responsible way.
