Participating in extreme activities is risky and may cause serious harm to your body or even endanger your life. We do not recommend you to try. Extreme activities such as skydiving, free rock climbing, high-speed racing, wing suit flying, deep-sea diving, etc., although they can bring a strong sense of excitement and an accelerated heartbeat and adrenaline rush, they are accompanied by great uncertainty and danger. If you want to experience a moderate accelerated heartbeat and excitement, you can choose some relatively safe sports or activities, such as running, cycling, taking spinning courses, trying exciting amusement facilities, etc., to ensure your own safety while enjoying the fun. Please always put safety first and avoid participating in dangerous and uncontrollable behaviors.
