High-altitude projects: glass plank road, canyon swing (choose a scenic spot with safety certification) **2. Psychologically challenging type (continuous tension)** 1. Immersive horror theater/script killing (choose an experience with safe words) 2. Learn high-risk skills: such as free diving (professional certification courses required) 3.
