Climbing a skyscraper without safety equipment is extremely dangerous and irrational. Here are some possible experiences and feelings, but please be aware that this behavior is a serious threat to life safety and is absolutely not recommended: 1. **Adrenaline Rush**: During the climbing process, you may feel a strong sense of excitement and tension because your body will release a lot of adrenaline. This feeling may make you temporarily ignore fear, but it also increases the risk. 2. **Fear and Anxiety**: When you realize that you are in an extremely dangerous environment, fear may arise spontaneously. Any moment of carelessness may have fatal consequences. 3. **Physical Challenge**: Climbing a skyscraper without the help of professional equipment requires extremely high physical fitness. You need excellent strength, endurance and balance to support your own weight. 4. **Psychological Pressure**: Aware of the potential life-threatening dangers and possible legal consequences, the psychological pressure will be extremely great. 5. **Loss of Direction**: When working at height, especially without fixed points and safety ropes, it is easy to feel disoriented and lose your sense of spatial position, which may lead to wrong decisions. 6. **Loneliness**: Climbing is usually done alone, without a support group or anyone around to help you, and this sense of isolation can increase fear and anxiety. Remember, safety always comes first. Climbing skyscrapers is done by professional climbers who have undergone rigorous training and use appropriate equipment, but even they are at risk. Doing this activity without training and safety equipment is extremely dangerous and illegal.
